TPS3423CAHDFADRLR TI Supervisory Circuit | SOT-583 | 1.8V-5.5V, 4.63V Threshold

Product Overview

The TPS3423CAHDFADRLR from Texas Instruments is a high-performance supervisory circuit designed for voltage monitoring in digital systems. Housed in a compact SOT-583 package, this device provides a precise reset output during power-up, power-down, and brown-out conditions. It operates over a wide supply voltage range of 1.8V to 5.5V, making it suitable for various low-power and portable applications. The device features a fixed threshold voltage of 4.63V, ensuring reliable system reset when the supply drops below this level. With a low quiescent current of typically 10µA, it is ideal for battery-powered equipment. The TPS3423CAHDFADRLR offers a manual reset input and an open-drain active-low reset output, providing flexibility in system design.
