The TPS3820-50DBVT is a Supervisory Circuit with active-low push-pull output and manual reset. 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.
