Working Principles

The MAX643AEPA+ operates by comparing the input voltage (TRIP) with the selected threshold voltage (TH). If the input voltage falls below the threshold, the active-low reset output (RESET) is triggered. The manual reset input (MR) allows for system control and can override the voltage monitoring function.
