[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] Embodiments of the present application provide a power-on circuit and device for reducing power consumption.

[0029] The power-on circuit is a widely used circuit. In order to make the power-on circuit work, a sliding switch and a processing module in the power-on circuit are used to implement power-on detection. However, in the existing scheme, when the power is turned off and not charged, the processing module in the power-on circuit needs to consume electric energy to maintain operation, and the power-on detection is performed based on the interrupt trigger mode of the processing module. Such a processing module is not in a stopped working state and still has a certain power consumption. In order to solve the above problems, the present application provides a power-on circuit and a device, which can implement power-on detection based on the circuit structure of the judgment module in the power-on circuit, and keep the processing module in a power-off state and stop working when the power is turned off and not charged, which greatly reduces the power consumption and brings a better experience to the user.

[0030] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] The terms "first", "second", "third", "fourth", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0032] The following is a description of a power-on circuit of the present application. Figure 1 , an embodiment of a power-on circuit of the present application includes: a detection module, a power-on module, a judgment module and a processing module;

[0033] Each of the detection module, the startup module, the judgment module and the processing module is connected to the other three modules, and the charging end is connected to the judgment module and the processing module respectively. The charging end is used for charging, and can be charged when the charging end is at a high level, and cannot be charged when the charging end is at a low level.

[0034] The detection module is used to detect the gear position of the sliding switch and send the detection signal corresponding to the gear position to the judgment module. The judgment module is used to control the power-on module to send a low-level drive signal to the processing module when the detection signal corresponds to the shutdown gear, the charging terminal is at a low level and the self-locking signal output by the processing module is at a low level, so that the processing module remains in a power-off state. The power-on circuit has at least two gears, one shutdown gear and at least one power-on gear. The sliding switch is in the shutdown gear, which indicates that the power-on circuit is in the shutdown state. The low level of the processing module self-locking signal indicates that the processing module is not working.

[0035] The working principle of this embodiment is now described. The user can slide the slide switch to put the power-on circuit in different gears. When the slide switch is in the power-off gear, it means that the power-on circuit is turned off. If the user does not plug the charger into the power-on circuit, there is no electrical signal at the charging end, the charging end is at a low level, and the self-locking signal of the processing module is at a low level, it means that the power-on circuit is now in a power-off and non-charging state. The judgment module controls the power-on module based on the circuit structure and the levels of the above three signals. The power-on module keeps the processing module in a power-off state, that is, the processing module does not work.

[0036] In the embodiment of the present application, the judgment module of the power-on circuit can obtain the detection signal and make a judgment based on the circuit structure. Only when the detection signal corresponds to the shutdown position, the charging end is at a low level and the self-locking signal output by the processing module is at a low level (that is, the power is turned off and not charged), the processing module remains in a power-off state, that is, stops working. In this way, basically no electrical energy is consumed, and power-on detection can be realized, thereby reducing power consumption and bringing a better experience to users.

[0037] It is understandable that the detection module includes at least two sliding switch positions, one of which is a power-off position and at least one power-on position. The number of positions can be set according to actual needs and is not limited here. The following description is based on five positions, namely, one power-off position and four power-on positions. Figures 2 to 5 , another embodiment of a power-on circuit of the present application includes: a detection module, a power-on module, a judgment module and a processing module;

[0038] Each of the detection module, the startup module, the judgment module and the processing module is connected to the other three modules, and the charging terminal VCHARGE is connected to the judgment module and the processing module respectively. The charging terminal VCHARGE is used for charging. When the charging terminal VCHARGE is at a high level, charging is possible, and when the charging terminal VCHARGE is at a low level, charging is not possible.

[0039] The detection module is used to detect the gear position of the sliding switch and send the detection signal corresponding to the gear position to the judgment module. The judgment module is used to control the power-on module to send a low-level drive signal to the processing module when the detection signal corresponds to the shutdown gear, the charging terminal VCHARGE is at a low level and the self-locking signal output by the processing module is at a low level, so as to keep the processing module in a power-off state.

Specifically, the first end of the first resistor R1 is used as the VIN end, that is, the input end of the processing module. The twelfth pin, the eleventh pin, the ninth pin, the eighth pin and the seventh pin are respectively one gear position, wherein the tenth pin is the off gear position, and the other four are the on gear positions. For example, when the slide switch slides to the off gear position, the tenth pin is connected to the ninth pin, and when the slide switch slides to the on gear position MODE1, the tenth pin is connected to the twelfth pin.

[0042] The power-on module includes: a PMOS tube Q1, a switch tube Q2, a fifth resistor R5, a sixth resistor R6 and a seventh resistor R7;

[0043] The source of the Pmos tube Q1 is respectively connected to the battery terminal VBAT and one end of the fifth resistor R5, the other end of the fifth resistor R5 is respectively connected to the gate of the Pmos tube Q1 and the third end of the switch tube Q2, the drain of the Pmos tube Q1 is respectively connected to the startup module and the processing module, the second end of the switch tube Q2 and one end of the sixth resistor R6 are both grounded, the other end of the sixth resistor R6 is respectively connected to the first end of the switch tube Q2 and one end of the seventh resistor R7, and the other end of the seventh resistor R7 is connected to the judgment module. Specifically, the drain of the Pmos tube Q1 serves as the VIN terminal.

[0044] The switch tube Q2 may be an NPN tube, an NMOS tube, or other tubes, which are not limited here. In one embodiment, the switch tube Q2 is an NPN tube, the base of the NPN tube serves as the first end of the switch tube Q2, the collector of the NPN tube serves as the third end of the switch tube Q2, and the emitter of the NPN tube serves as the second end of the switch tube Q2.

[0045] The judgment module includes: an OR gate, an eighth resistor R8, a ninth resistor R9 and a tenth resistor R10;

[0046] The output end of the OR gate is connected to the power-on module, the VCC end of the OR gate is respectively connected to one end of the eighth resistor R8 and the battery end VBAT, the other end of the eighth resistor R8 is respectively connected to the first input end of the OR gate, the detection module and the processing module, the second input end of the OR gate is connected to the charging end VCHARGE via the tenth resistor R10, the third input end of the OR gate is respectively connected to one end of the ninth resistor R9 and the processing module, the other end of the ninth resistor R9 is grounded, and the ground end of the OR gate is grounded. Specifically, the fourth pin of the OR gate is the output end, connected to the seventh resistor R7, the other end of the eighth resistor R8 is connected to the ninth pin of the detection module, and the first input end, the second input end and the third input end of the OR gate are respectively the first pin, the second pin and the third pin of the OR gate.

[0047] The first input terminal of the OR gate serves as the PSTA terminal.

[0048] The processing module includes: an eleventh resistor R11, a twelfth resistor R12, a power management unit and a processing unit;

[0049] The processing unit is provided with an input terminal, an output terminal, a first detection terminal and a second detection terminal. The input terminal of the processing unit is connected to the power-on module and the detection module respectively through the power management unit. The output terminal and the first detection terminal of the processing unit are connected to the judgment module. The charging terminal VCHARGE is connected to one end of the twelfth resistor R12 and the second detection terminal of the processing unit respectively through the eleventh resistor R11. The other end of the twelfth resistor R12 is grounded, and the processing unit is connected to the detection module. Among them, the power management unit is a voltage conversion chip or a driver chip, and can also be other, which is not limited here. The processing unit only works when the VIN terminal is at a high level. After the processing unit works, it will detect the voltage of the PSTA terminal (first detection terminal) and the twelfth resistor R12 (second detection terminal).

[0050] The detection working principle of this embodiment is now described. When the power-on circuit is in the off state and not charged, the slide switch is in the off position, the ninth pin and the tenth pin of the connector SW1 are connected, that is, the POWER_HOLD_SW end is grounded, and the current flows from the battery end VBAT through the eighth resistor R8 to the ground. The POWER_HOLD_SW end is low level, that is, the first pin of the OR gate is low level, and at the same time, the charging end VCHARGE is low level, then the second pin of the OR gate is also low level, and the processing unit has not yet worked, so the POWER_HOLD_MCU end is low level, that is, the sixth pin of the OR gate is low level, and the OR gate outputs a low level according to the level of the first pin, the third pin and the sixth pin, that is, the POWER_ON / OFF_CTL end is low level, and the NPN tube is cut off, which causes the Pmos tube Q1 to be cut off, and the VIN end is low level, so the processing unit remains in the power-off state. When the power-on circuit is in the power-on but not charging state, the slide switch is in the power-on position (for example, the MODE1 position), the tenth pin and the twelfth pin of the connector SW1 are connected, and the POWER_HOLD_SW end is not grounded, so the level of the first pin of the OR gate is pulled up by the eighth resistor R8 and is a high level. At this time, the OR gate outputs a high level, that is, the POWER_ON / OFF_CTL end is a high level, the NPN tube is turned on, the Pmos tube Q1 is turned on, the VIN end is a high level, the processing unit works, and the POWER_HOLD_MCU end is controlled to be a high level, forming a self-locking. When the power-on circuit is in the shutdown charging state, the slide switch is in the shutdown position, the ninth pin and the tenth pin of the connector SW1 are connected, the POWER_HOLD_SW end is grounded, the POWER_HOLD_SW end is low level, that is, the first pin of the OR gate is low level, and at the same time the charging end VCHARGE is high level, then the output of the OR gate is high level, that is, the POWER_ON / OFF_CTL end is high level, the NPN tube is turned on, the Pmos tube Q1 is turned on, the VIN end is high level, the processing unit works, and the POWER_HOLD_MCU end is controlled to be high level, forming a self-locking. When the power-on circuit is in the power-on charging state, the POWER_HOLD_SW terminal and the charging terminal VCHARGE are both high levels, that is, the first pin and the third pin of the OR gate are both high levels, and the OR gate outputs a high level, that is, the POWER_ON / OFF_CTL terminal is high, the NPN tube is turned on, the Pmos tube Q1 is turned on, the VIN terminal is high, the processing unit works, and the POWER_HOLD_MCU terminal is controlled to be high, forming a self-locking.

[0051] The working principle of the processing unit of this embodiment is now explained. When the power-on circuit is in the power-off and uncharged state, the processing unit remains in the power-off state and basically has no power consumption. When the power-on circuit is in the power-on and uncharged state, the power-off and charging state, or the power-on and charging state, the processing unit works and controls the POWER_HOLD_MCU terminal to be high level to form a self-locking state. At the same time, the processing unit starts to detect the first detection terminal (PSTA terminal) and the second detection terminal (twelfth resistor R12): If the power-on circuit is turned to the power-off and uncharged state, the levels of the PSTA terminal and the twelfth resistor R12 are both low levels. After a delay of a period of time, the processing unit sets the POWER_HOLD_MCU terminal to a low level, or the gate outputs a low level, and the processing unit is powered off; If the power-on circuit is switched to the shutdown charging state, the PSTA terminal is at a low level and the charging terminal VCHARGE is at a high level, so the level of the twelfth resistor R12 is at a high level. The processing unit notifies the device to turn off the peripherals after a delay, while keeping the POWER_HOLD_MCU terminal at a high level; if the power-on circuit is switched to the power-on non-charging state or the power-on charging state, the PSTA terminal is at a high level, the charging terminal VCHARGE is at a high level or a low level, the processing unit keeps the POWER_HOLD_MCU terminal at a high level, the device is fully powered on, and self-locking is formed.

[0052] In this embodiment, the OR gate of the power-on circuit can make a judgment based on the signal corresponding to the gear position, the signal of the charging terminal VCHARGE and the self-locking signal of the processing unit. Only when the detection signal corresponds to the shutdown gear position, the charging terminal VCHARGE is at a low level and the self-locking signal output by the processing module is at a low level (i.e., the power is turned off and not charged), the processing module is kept in a power-off state, that is, it stops working. In this way, basically no power is consumed, and power-on detection can be realized, which reduces power consumption, soft shutdown and hard power off, bringing a better experience to users. In addition, the processing unit is provided with a delay function to prevent accidental touches and improve the fault tolerance rate.
