Application of 555 Timer Output Power Off Delay Start Circuit in Power Supply Field
To ensure the reliability of the system,it is necessary to perform power on timing control to ensure that each functional circuit module is powered on in sequence. In order to avoid causing power on timing disorder,a power off delay start circuit based on 555 timer output is designed. This circuit has the advantages of low usage of components,controllable delay time,and controllable power output enabling pins. Compared with direct control of power output,it is safety,reliability,simple,and low cost.
