产品描述

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 (VDD) becomes higher than 0.4 V. Thereafter, the supervisory circuit monitors VDD and keeps the 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 to ensure proper system reset. The delay time starts after VDD has risen above VIT. When VDD drops below VIT, the output becomes active again.

All the devices of this family have a fixed-sense threshold voltage (VIT) 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.
