Working Principles

The MAX8216CSD+T is designed to monitor the supply voltage and generate a reset signal when the voltage falls below the programmed threshold. It operates by comparing the input voltage (TH) with an internal reference voltage. When the input voltage drops below the threshold, the reset output (RESET) is activated, indicating a power failure or low voltage condition. The manual reset input (MR) allows external control of the reset signal, providing flexibility in system design.
