Remark

TLC7705QD General Description

The TLC7705QD is a low-power voltage detector IC designed for use in microprocessor systems, providing power-on reset and watchdog timer functions. It features a supply voltage range of 2.7V to 5.5V and consumes only 5µA of quiescent current, making it suitable for battery-powered applications.This IC has a built-in supervisor circuit that monitors the power supply voltage and generates a reset signal when the voltage falls below a certain threshold. This ensures a controlled start-up sequence and prevents the microprocessor from operating in an undefined state.Additionally, the TLC7705QD includes a watchdog timer that monitors the system's operation and generates a reset signal if the microprocessor fails to respond within a specified time period. This helps prevent software hangs and ensures the system remains operational.

Features

The TLC7705QD is a voltage supervisor with a fixed threshold voltage of 4

55V, ideal for monitoring power supply voltages in microcontroller systems

It features a manual reset input, active-low reset output, and a low supply current of 25uA

The device is available in a 8-pin SOIC package

Application

The TLC7705QD is commonly used in power supply monitoring and battery management systems, as well as in industrial automation and control systems

It is also suitable for use in automotive electronics and consumer electronics, where low-power consumption and high reliability are important considerations
