TPS389020DSET TI Supervisory Circuit | 6-WSON (1.5X1.5) | 0.5% Threshold Accuracy, 2.7V-5.5V

Product Overview

The TPS389020DSET from Texas Instruments is a high-accuracy supervisory circuit designed for monitoring power supply voltages in a wide range of applications. Housed in a compact 6-WSON (1.5mm x 1.5mm) package, this device offers precise voltage monitoring with a threshold accuracy of 0.5% typical. It operates over a supply voltage range of 2.7V to 5.5V, making it suitable for low-voltage systems. The TPS389020DSET features an active-low open-drain reset output with a fixed delay time of 200ms, ensuring reliable system reset during power-up, power-down, and brownout conditions. Its ultra-low quiescent current of 5µA (typical) makes it ideal for battery-powered applications.
