High-voltage delay-on circuit based on 555 chip design

Probe high frequency needle 10445 with line high frequency needle with 1 high frequency core can pass 3A

Memory chip

At the moment when the power is turned on, since the voltage on C2 cannot be abrupt, but for short circuit, the 2 and 6 feet are at a high level, so that 555 is reset, and the output of the 3 pin is low. At the same time, C2 starts to charge. When it is charged to 2 feet and 1/3 VDD level, 555 is valued, 3 feet is turned to high level, K is pulled, and high voltage is turned on. The charging time of C2, that is, the startup delay time td=1.1R2C2, the graphical parameter is about 2 minutes.
Adjust the RC charging time constant to change the high voltage on time.
