Working Principles

ADM1293-1AACPZ operates by continuously monitoring the input voltage, output voltage, and load current. It compares these values against user-defined thresholds to detect faults such as overvoltage, undervoltage, overcurrent, and overtemperature conditions. When a fault is detected, the device reports it through the ALERT pin and sets the FAULT pin low. The I2C interface allows users to configure various parameters and customize the power sequencing behavior.
