The is a Supervisory Circuit with active-low open-drain output. The supervisory circuit provides circuit initialization and timing supervision, primarily for DSPs and processor-based systems. During power on, /RESET is asserted when supply voltage VDD becomes higher than 1.1V. 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 high to ensure proper system reset. The delay time td of 25ms typical, starts 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. It has a fixed-sense threshold voltage VIT set by an internal voltage divider.
