Working Principles

The MAX631ACPA operates by comparing the power supply voltage with a selected threshold voltage. When the supply voltage drops below the threshold, the reset output is activated. The reset signal remains active until the supply voltage rises above the threshold or a manual reset is applied. The reset timeout period can be adjusted using an external capacitor connected to the CT pin.
