Thereafter, the supervisory circuit monitors VDD and keeps the RESET pin active as long as VDD remains below the threshold voltage (VIT). An internal timer delays the return of the output to the inactive (high) state to ensure proper system reset. The delay time, td = 25 ms typical, begins after VDD has risen above the threshold voltage (VIT). When the supply voltage drops below the threshold voltage (VIT), the output becomes active (low) again. No external components are required. All the devices of this fa...
