Формирователи импульса сброса TL7702ACP .

Схема контроля напряжения , активный высокий, выход сброса с активным низким, 3.5В-18В (Vin), DIP-8

The TL7702ACP is a single-supply Voltage Supervisor with programmable UV threshold and reset time delay. Designed specifically for use as reset controllers in microcomputer and microprocessor systems. The supply-voltage supervisor monitors the supply for under-voltage conditions at the SENSE input. During power up, the RESET output becomes active (low) when VCC attains a value approaching 3.6V. At this point (assuming that SENSE is above VIT+), the delay timer function activates a time delay, after which outputs RESET and RESET go inactive (high and low, respectively). When an under-voltage condition occurs during normal operation, RESET and RESET go active.

• Power-on reset generator
