TPS3809I50QDBVRQ1 TI Supervisory Circuits | SOT-23-3 | 4.65V Threshold, Active-Low Reset

Product Overview

The TPS3809I50QDBVRQ1 from Texas Instruments is a supervisory circuit designed for monitoring power supplies in automotive and industrial applications. It provides a precision voltage monitor with a fixed threshold of 4.65V, ensuring reliable reset generation during power-up, power-down, and brown-out conditions. Housed in a compact SOT-23-3 package, this device offers a low-power solution with a typical supply current of 2.2 µA. The active-low reset output remains asserted for a minimum of 140 ms after VDD rises above the threshold, providing system stability.
