During power-on, RESET is asserted when the supply voltage (VDD) becomes higher than 1.1 V. Thereafter, the supervisory circuit monitors VDD and keeps RESET active as long as VDD remains below the threshold voltage VIT. An internal timer delays the return of the output to the inactive state (low) to ensure proper system reset. The delay time (td(typ) = 200 ms) starts after VDD has risen above the thresh...
