TPS3809K33MDBVREP TI Supervisory Circuit | SOT-23-3 | 3.3V Threshold, Active-Low Reset

Product Overview

The TPS3809K33MDBVREP from Texas Instruments is a supervisory circuit designed for monitoring power supplies in digital systems. It provides a precision voltage monitor with a fixed threshold of 3.3V, ensuring reliable reset generation during power-up, power-down, and brown-out conditions. Housed in a compact SOT-23-3 package, this device is ideal for space-constrained applications requiring high accuracy and low power consumption. The TPS3809K33MDBVREP features an active-low, open-drain reset output that remains asserted for a minimum of 140ms after the supply voltage rises above the threshold, allowing the system to stabilize.
