Working Principles

ADM1170-2AUJZ-RL7 operates by measuring the voltage drop across a sense resistor connected in series with the load. This voltage drop is proportional to the current flowing through the load. The device converts this voltage into a digital value, which can be accessed through the I2C/SMBus interface. It continuously monitors the current and compares it against user-defined thresholds to detect overcurrent or undervoltage conditions. When a fault is detected, the ALERT pin is activated to indicate the fault condition.
