TL7702BCD TI Supervisory Circuits | 8-SOIC | 2.53V Threshold, Active-Low Reset

Product Overview

The TL7702BCD from Texas Instruments is a supply voltage supervisor circuit designed to monitor power supply voltages in digital systems. It provides a reset signal to the microprocessor or microcontroller whenever the supply voltage drops below a preset threshold, ensuring reliable system operation during power-up, power-down, and brown-out conditions. Housed in an 8-pin SOIC package, this device features a precision voltage reference and a comparator with hysteresis to prevent false triggering. The TL7702BCD is ideal for applications requiring high accuracy and low power consumption.
