DESCRIPTION
The TPS3836, TPS3837, TPS3838 families of supervisory circuits provide circuit initialization and timing
supervision, primarily for digital signal processing (DSP) and processor-based systems.
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
reset. The delay time starts after VDD has risen above VIT.
When CT is connected to GND, a fixed delay time of typical 10 ms is asserted. When connected to VDD, the
delay time is typically 200 ms.
