Working Principles

The MAX706SCUA+T is designed to monitor the power supply voltage of a microprocessor-based system. It compares the supply voltage with a selected threshold voltage and generates a reset signal when the voltage falls below the threshold. The reset signal remains asserted until the supply voltage rises above the threshold or a manual reset input is activated.
