AI Technical Summary

Problems solved by technology

[0007] (1) When the battery is inserted into the battery connector 10, a bouncing signal will be generated, causing the electronic product to start operating, but the power supply is unstable, which may easily lead to an unstable situation in the electronic product
[0008] (2) When the battery is pulled out of the battery connector 10, a bouncing signal will be generated, causing the power supply to be unstable when the electronic product is to be turned off, which may easily lead to an unstable situation of the electronic product

Embodiment Construction

[0020] FIG. 3 is a schematic diagram of a control circuit for debounce signal generation according to a preferred embodiment of the present invention. The control circuit includes: the input terminal 401 of the charging and discharging circuit 40 is coupled to the battery connector 30 for storing charge when the input terminal 401 has a voltage input, and releasing the charge when the input terminal 401 has no voltage input. Next, the flip-flop 50 has four input terminals and two output terminals, wherein the preset terminal and the data terminal are coupled to the voltage source, the clear terminal is coupled to the battery connector 30, and the clock pulse input terminal is coupled to the charging and discharging terminal. The data output from the output terminal 403 of the circuit 40 and the two output terminals of the flip-flop 50 are complements of each other. As those skilled in the art know, the flip-flop 50 can be a D-type flip-flop, but not limited thereto.

Abstract

The control circuit for eliminating bounce includes charge and discharge circuit and D-flip flop. When the electronic product is connected with or disconnected from the battery, the control circuit for eliminating bounce has its charge and discharge circuit charging or discharging to control the level of the clock end in the D-flip flop and to provide the electronic product with stable voltage so as to eliminate the instability of power source voltage caused by bounce.

Description

technical field [0001] The present invention relates to a control circuit, and in particular to a control circuit for eliminating bounce signal generation. Background technique [0002] With the rapid development of science and technology, various electronic products are becoming more and more popular. At the same time, because people use electronic products whether they are working or leisure, all electronic products are developing towards light, thin, short and small, and can make Users use it anytime and anywhere, so most of the portable electronic products are equipped with batteries for convenient use. When the user replaces the battery of an electronic product, when the battery is inserted or pulled out, a so-called bouncing signal will be generated, resulting in unstable power supply. If it is not handled properly, it will easily lead to system instability. [0003] FIG. 1 shows a schematic diagram of a conventional power supply connection of an electronic product. T...
