Working Principles

The MAX6315US48D2-T operates by continuously monitoring the supply voltage connected to the VCC pin. It compares the voltage against the selected threshold voltage (determined by the TH pin) and generates a reset signal when the voltage falls below this threshold. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered through the MR pin.
