TPS389012DSER TI Supervisory Circuits | 6-WSON (1.5x1.5) | 0.5% Threshold Accuracy, 10ms Delay

Product Overview

The TPS389012DSER from Texas Instruments is a high-accuracy, low-power supervisory circuit designed for monitoring power supply voltages in a wide range of applications. It features a precision voltage reference and a comparator that monitors the SENSE pin for undervoltage conditions. When the voltage at SENSE drops below the threshold, the RESET output asserts low. The device offers a fixed threshold voltage of 1.2V with 0.5% accuracy over temperature, and a built-in delay time of 10ms (typical) to prevent false resets. Housed in a compact 6-WSON (1.5x1.5mm) package, it is ideal for space-constrained designs.
