Working Principles

The MAX6832GXRD3+T operates by continuously monitoring the power supply voltage. When the voltage falls below the selected threshold, it generates a reset signal on the RESET pin. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered through the MR pin. The reset timeout period can be adjusted using an external capacitor connected to the CT pin.
