Abstract
The utility model relates to an automatic reset circuit for power supply, comprising a CPU reset terminal, a battery power source (V1). The utility model is characterized in that the CPU reset terminal is connected with the emitter electrode of a triode (Q1), the base electrode of the triode (Q1) is connected with the emitter electrode of a triode (Q2), the base electrode of the triode (Q2) is connected in parallel with one end of a resistor (R) and then is connected with the positive electrode of the battery power source (V1), and the other end of the resistor (R), the collector electrodes of the triode (Q1) and the triode (Q2) are all connected with the ground. When used, the utility model can nicely solve the ubiquitous dead halt phenomena of similar control circuits such as the remote controller of an air conditioner, and the working speed and the reliability of equipment can be enhanced.
Description
The utility model relates to electronic technology field, particularly a kind ofly utilizes battery powered computer circuits automatic reset circuit.
The configuration of existing air conditioner form telepilot or other similar control electrical equipment of control circuit by single-chip microcomputer, endless loop appears when power source change easily, at this moment must carry out manual reset, use pretty troublesome.
The purpose of this utility model provides a kind of automatic power-on reset circuit.
For reaching above-mentioned purpose, take following technical scheme: the sampling of the potential change that occurs during with battery altering, be transferred to the reset terminal of control circuit through processing and amplifying, make it that homing action take place.
By above technical scheme, circuit just endless loop can not occur, has improved the operating rate and the reliability of circuit.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the wiring diagram that the utility model is used on the air conditioner remote control circuitry.
