Description
AI
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,RESETis asserted when the supply voltage VDDbecomes higher than 1.1 V. Thereafter, the supervisory circuit monitors VDDand keepsRESEToutput active as long as VDDremains 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 VDDhas 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.
When the supply voltage drops below VIT, the output becomes active (low) again.
All the devices of this family have a fixed-sense VITset by an internal voltage divider.
The TPS3836 has an active-low push-pullRESEToutput. The TPS3837 has active-high push-pull RESET, and the TPS3838 integrates an active-low open-drainRESEToutput.
The product spectrum is designed for supply voltages of 1.8 V, 2.5 V, 3 V, and 3.3 V. The circuits are available in a 5-pin SOT-23 package. The TPS3836, TPS3837, and TPS3838 families are characterized for operation over a temperature range of –55°C to 125°C.
