During power on, RESET is asserted when the supply voltage VDD bees higher than 1.1 V. Thereafter, the supervisory circuit monitors VDD and keeps RESET output active as long as VDD remains below the threshold voltage (VIT). An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset. The delay time starts after VDD has risen above VIT. When CT is connected to GND, a fixed delay time of typical 10 ms is asserted. When connected to VDD, the delay time is typically 200...
