The is a Supervisor Circuit with active-low and active-high push-pull output. The supervisor provides circuit initialization and timing supervision, primarily for DSP and processor-based systems. During power on, /RESET asserts when the supply voltage VDD becomes greater than 1.1V. Thereafter, the supply voltage supervisor monitors VDD and keeps /RESET active low as long as VDD remains less than 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, starts after VDD has risen above the threshold voltage VIT-+ VHYS. 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.
