The TPS310x and TPS311x families of supervisory circuits provide circuit initialization and timing supervision, primarily for DSP and processor-based systems.

During power-on, RESET is asserted when the supply voltage (V_DD) becomes higher than 0.4 V. Thereafter, the supervisory circuit monitors V_DD and keeps the RESET output active as long as V_DD remains below the threshold voltage (V_IT). An internal timer delays the return of the output to the inactive state to ensure proper system reset. The delay time starts after V_DD has risen above V_IT. When V_DD drops below V_IT, the output becomes active again.

All the devices of this family have a fixed-sense threshold voltage (V_IT) set by an internal voltage divider.

The TPS3103 and TPS3106 have an active-low, open-drain RESET output. The TPS3110 has an active-low push/pull RESET.

The product spectrum is designed for supply voltages of 0.9 V up to 3.3 V. The circuits are available in SOT23-6 packages. The TPS31xx family is characterized for operation over a temperature range of -55°C to 125°C.
