Working Principles

The MAX810REUR-T operates by continuously monitoring the supply voltage connected to the VCC pin. When the voltage falls below the specified threshold, the RESET pin is asserted, indicating a low-voltage condition. Once the supply voltage rises above the threshold, the RESET pin is deasserted, signaling that the voltage has returned to an acceptable level. The reset timeout period ensures that momentary voltage dips do not trigger unnecessary resets.
