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 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 rese...
