TPS389001DSER TI Supervisory Circuits | 6-WSON (1.5X1.5) | 0.5% Accuracy, 1.8V to 5.5V

Product Overview

The TPS389001DSER 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 generates a reset signal when the monitored voltage falls below a preset threshold. Housed in a compact 6-WSON (1.5x1.5 mm) package, it is ideal for space-constrained designs.
