说明

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.
