Working Principles

The S-8264AAT-I8T1U is a voltage detector IC designed to monitor the supply voltage and provide an output signal based on a preset detection voltage. It incorporates a delay circuit that allows a user-defined delay time before the output changes state. The built-in output driver can directly control external devices, such as power switches or microcontrollers. The soft-start function gradually increases the output voltage during power-up, reducing stress on the system components. The manual reset pin provides a means to immediately reset the system when triggered.
