TPS3103 Datasheet (Texas Instruments) - Ultralow Supply-Current Voltage Monitor

TPS3103, Ultralow Supply-Current Voltage Monitor

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 low when the supply voltage (VDD) becomes higher than 0.4 V.

Thereafter, the supervisory circuit monitors
