Product Introduction

Overview

The TPS3823-33QDBVRQ1 is a voltage monitor with a watchdog timer, designed and manufactured by Texas Instruments. This component is part of the TPS382x-xx-Q1 family, which provides circuit initialization and timing supervision, primarily for DSP and processor-based systems. It monitors a single supply voltage and issues a reset signal when the voltage falls below a preset threshold, ensuring proper system reset and protection of sensitive digital circuits.
