Working Principles

The MAX8213BCSE operates by continuously monitoring the input voltage and comparing it with the threshold voltage set by the TH pin. If the input voltage falls below the threshold voltage, the output signal is activated (either active-low or active-high). The MR pin allows for manual reset of the device. The low quiescent current ensures minimal power consumption, making it suitable for battery-powered applications.
