Embodiment Construction

[0040] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0041] When using electronic products, you usually encounter the problem of electronic products crashing. For example, if there are many windows opened on the computer, and many applications are opened on the mobile phone, etc., it will cause the electronic product to crash, and then cause the electronic product to fail to work normally. When the electronic p...

Abstract

The invention provides a reset circuit, a chip and an electronic product. According to the reset circuit provided by the embodiment of the invention, when the electronic product crashes, a user only needs to repeatedly perform the operation of connecting the charging interface with the external power supply and then disconnecting the charging interface, and when a charging detection unit detects that the charging and power-off times of the electronic product within the preset duration through the charging interface are greater than or equal to the preset times, a first signal is sent to a reset control unit to enable the reset control unit to control the electronic product to reset. A physical key for resetting is not required to be arranged, so that the cost and size of the electronic product are reduced. Moreover, whether the electronic product crashes or not does not need to be detected by outputting a clock signal regularly when the electronic product works normally, so that unnecessary power consumption waste is avoided. According to the reset circuit provided by the embodiment of the invention, the electronic product does not need to be charged and restarted after autonomousdischarging is finished, restarting can be realized through the reset circuit after the electronic product is halted, and the user experience is improved on the basis of reducing the power consumption.

Description

technical field [0001] The present application relates to the field of circuit technology, in particular to a reset circuit, chip and electronic product. Background technique [0002] The current electronic products, such as mobile phones, tablet computers, wearable devices, etc., may cause electronic product crashes due to system software runaway or improper operation during use, and then cause electronic products to fail to work normally. Operations such as restart or reset. [0003] Existing electronic products, when there is a crash problem, usually use the watchdog (Watch Dog) reset technology to reset and restart. The principle is: the Watch Dog chip outputs a clock signal to the system at regular intervals. The clock signal will not be received within the time period, at this time, a restart or reset of the system will be triggered. [0004] For the Watch Dog reset technology, the Watch Dog chip needs to continuously output clock signals to the system, resulting in ...
