TPS3825, TPS3820 Datasheet (Texas Instruments)

TPS3825, TPS3820, Voltage Monitor

The TPS382x family of supervisors provide circuit initialization and timing supervision, primarily for DSP and processor-based systems.

During power on, RESET asserts when the supply voltage VDD becomes greater than 1.1 V.

Thereafter, the supply voltage supervisor monitors VDD and keeps RESET active
