TPS3825-33QDBVRQ1 TI Supervisory Circuit | SOT-23-5 | 2.63V Threshold, 200ms Reset

Product Overview

The TPS3825-33QDBVRQ1 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 threshold of 2.63V (for 3.3V systems) and a fixed reset timeout of 200ms. Housed in a compact SOT-23-5 package, this device ensures reliable system reset during power-up, power-down, and brownout conditions. It features a manual reset input and an open-drain reset output, making it ideal for use with microcontrollers, DSPs, and other digital systems requiring a clean reset signal.
