General Description

The ADM1178 is an integrated hot swap controller and current sense amplifier that offers digital current and voltage monitoring via an on-chip, 12-bit analog-to-digital converter (ADC), communicated through an I2C interface.

An internal current sense amplifier senses voltage across the sense resistor in the power path via the VCC pin and the SENSE pin.

The ADM1178 limits the current through this resistor by controlling the gate voltage of an external N-channel FET in the power path, via the GATE pin.
