Working Principles

The MAX823SEUK+TG002 is designed to monitor the supply voltage of a system. It compares the input voltage with a reference threshold voltage and generates a reset signal when the voltage falls below the specified threshold. The device operates in low-power mode, consuming minimal current during normal operation. The manual reset input allows for system initialization or recovery by forcing the reset output to a logic low state. The open-drain reset output can be connected to a microcontroller or other devices for system-level monitoring.
