TL7702BIDRE4

Product Overview

Category: Integrated Circuits (ICs)

Use: TL7702BIDRE4 is a voltage supervisor and reset IC. It monitors the power supply voltage of a system and generates a reset signal when the voltage falls below a predetermined threshold. This ensures proper operation of the system by resetting it when the power supply voltage is insufficient.

Characteristics: - Low power consumption - Wide operating voltage range - Adjustable reset threshold - Precision voltage reference - Open-drain output - Small package size

Package: TL7702BIDRE4 is available in a small 8-pin SOIC (Small Outline Integrated Circuit) package.

Essence: The essence of TL7702BIDRE4 lies in its ability to monitor the power supply voltage and generate a reset signal, ensuring reliable operation of electronic systems.
