Control device and method of circuit system

Abstract

The invention provides a control device of a circuit system. The control device comprises a main power supply circuit, a main controller circuit, a switch driving circuit, a switch module, a wake-up circuit and a non-wake-up circuit, wherein the main power supply circuit is respectively connected with the main controller circuit, the switch driving circuit and the wake-up circuit, the main power supply circuit is also connected with the non-wake-up circuit through the switch module, and when a circuit system enters a low-power-consumption state, the main controller circuit sends a control signal to the switch driving circuit, the switch driving circuit controls the switch module to be switched off according to the control signal, and the main power supply circuit stops supplying power to the non-wake-up circuit. The invention further provides a control method of the circuit system. According to the control device and method of the circuit system, when the circuit system enters the low-power-consumption state, the non-wake-up circuit is completely powered off to achieve zero power consumption of the circuit, and the devices and chips of the non-wake-up circuit do not need to be selected from devices and chips in a sleep mode, so that the system cost is lower.

Description

【Technical field】 [0001] The invention relates to the technical field of circuit systems, in particular to a control device and method for a circuit system. 【Background technique】 [0002] With the development and progress of society, the problems caused by environmental pollution and energy waste have become more and more prominent, and energy conservation and emission reduction have attracted more and more attention from the state and enterprises. In electronics, circuits, and electrical systems, there are many applications that are necessary for low power consumption and low loss of the system, such as: energy storage base station battery management system, electric vehicle or electric bicycle battery protection board management system, printer system, etc. When the battery is installed but the system load is not connected or there is no external command to perform operations, it should enter the low power consumption mode. [0003] However, some existing circuit systems...

AI Technical Summary

Problems solved by technology

[0003] However, some existing circuit systems or devices continue to work when they do not need to work, and there is a lot of waste of energy

There are also some circuit systems or devices that control all circuits through the processor to enter the sleep state when they do not need to work, and at the same time the processor enters the standby state. Some module circuits or devices in irrelevant circuits will not have low power consumption mode, such as resistors, capacitors, inductors, transistors, diodes and other components, some chips, etc., the equivalent resistance of these devices will cause power loss

In addition, even if these circuits that have nothing to do with wake-up signal generation have a low-power mode, the energy consumed by these circuits in low-power sleep is meaningless when the system does not need to work.

Moreover, in order to reduce the standby power consumption of the system, no matter whether it is a circuit related to the wake-up signal or not, a chip or device with a low power consumption mode function must be selected, resulting in a higher circuit cost
