Voltage level sensing power-up reset circuit

摘要: A power-up reset circuit for providing a signal resetting elements such as flip-flops upon the application of power to includes CMOS pair output section and capacitor coupled gates transistors. The is charged up by supply switch low level after operation has been achieved. In order accommodate slow ramping supplies, circuitry operating voltage sensitive included prevent from charging until reached sufficient ensure proper operation. fast rate controlled assure minimum necessary duration signal.
