Overview
The MAX708SESA-TG is a microprocessor supervisory circuit produced by onsemi. This device is designed to monitor the supply voltage (VCC) in digital systems and provide a reset signal to the host processor when necessary. It is part of the MAX707/708 series, which offers cost-effective solutions for system supervision. The MAX708SESA-TG is particularly useful in applications requiring precise voltage monitoring and reset functionality.
