UCC3946D TI Supervisory Circuit | 8-SOIC | 2.93V Threshold, Active-Low Reset

Product Overview

The UCC3946D from Texas Instruments is a precision supervisory circuit designed for monitoring power supply voltages in digital systems. It provides a reset output during power-up, power-down, and brownout conditions. The device features a fixed threshold voltage of 2.93V, ensuring reliable system reset when the supply voltage drops below this level. Housed in an 8-pin SOIC package, it is ideal for space-constrained applications requiring high accuracy and low power consumption.
