Embodiment 1

[0030] Please refer to figure 1 , this embodiment provides a wake-up detection circuit for a plug-in device, and the circuit includes an access terminal, a wake-up circuit, and a detection circuit. Among them, the access terminal is used to access external devices, such as earphones, the wake-up circuit is connected to the access terminal, and the wake-up circuit is used to detect the access resistance of external devices, such as figure 1 It is detected that the grounding resistance of the plug-in device is R1. When the grounding resistance R1 of the plug-in device is connected, the resistance value in the wake-up circuit changes, and then a wake-up signal is output, and the output terminal of the wake-up circuit (ie figure 1 The wake-up chip terminal in the terminal) is used to connect to the host chip, and the output wake-up signal is used to wake up the host chip in the standby state, thus avoiding the manual operation of the user to wake up the electronic device. The inp...

Embodiment 2

[0039] This embodiment provides a wake-up detection device for a plug-in device. The device includes the wake-up detection circuit provided in Embodiment 1. When the device detects that a plug-in device is connected, it can output a wake-up signal triggered by the access resistance of the plug-in device. Signal, the wake-up signal can wake up the host chip in the standby state, avoiding manual wake-up of the host device, making the operation more convenient. At the same time, the access resistance of the external device is obtained by detecting the detection chip connected to the chip end, and the device type of the external device is obtained according to the preset relationship between the access resistance and the device type, and the detected device type is sent to the host chip, so that The host chip can automatically establish a corresponding communication connection with the external device, which saves the user's manual operation process. The wake-up detection device ca...

Embodiment 3

[0041] An electronic product, the electronic product includes a wake-up detection circuit as provided in Embodiment 1, the electronics can be a mobile phone, a tablet computer, a smart wearable device, etc., when an external device is connected, triggered by the access resistance of the external device Output a wake-up signal, the wake-up signal can wake up the host chip in the standby state, avoiding manual wake-up of electronic equipment, making the operation more convenient. At the same time, the access resistance of the external device is obtained by detecting the detection chip connected to the chip end, and the device type of the external device is obtained according to the preset relationship between the access resistance and the device type, and the detected device type is sent to the host chip, so that The host chip can automatically establish a corresponding communication connection with the external device, saving the user's manual operation process.

Abstract

The invention relates to the technical field of electronic circuits, and particularly relates to a plug-in equipment awakening detection circuit and detection device and an electronic product. The awakening detection circuit comprises an access end, an awakening circuit and a detection circuit. The access end is used for accessing plug-in equipment; the awakening circuit is connected with the access end and used for detecting the access resistance of the plug-in equipment and outputting an awakening signal under triggering of the access resistance of the plug-in equipment, the output end of the awakening circuit is used for being connected with a host chip, the awakening signal is used for waking up the host chip in a standby state, manual wake-up of the host device is avoided, and operation is more convenient.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a wake-up detection circuit for plug-in equipment, a detection device and electronic products. Background technique [0002] With the development of electronic technology, smart electronic devices have been closely related to people's lives, but communication products such as mobile phones, if an external device (such as a headset) is plugged in when it is in a dormant state, it cannot automatically wake up and detect the external device. Therefore, it is impossible to actively establish a communication connection with the external device, and each time the user needs to manually release the dormant state, which increases the complexity of the operation. Contents of the invention [0003] The main technical problem to be solved by the present invention is that the existing electronic products cannot actively wake up in a dormant state. This embodiment provides a wak...
