产品详细说明

TPS3808G01DBVR is Texas Instruments' adjustable-threshold single-supply voltage supervisor in a six-pin DBV SOT-23 package.

Its G01 sense option uses a 0.405 V threshold with an external divider, allowing a board designer to set the monitored rail's trip point rather than accept one fixed nominal voltage.

When SENSE falls below threshold, the open-drain RESET output holds a processor in reset; it releases only after the selected delay, avoiding an early restart on a recovering rail.

The CT connection supports a capacitor-programmed delay from 1.25 ms to 10 s, and the manual-reset input gives a separate path to request the same reset action.

A 2.4 µA typical quiescent current limits supervisory overhead in battery-powered equipment, while the DBV package keeps the external timing and divider parts accessible.
