ADM1176-2ARMZ-R7 | Hot Swap Controller with I²C Power Monitor | ADI PMIC

Product Overview

     The ADM1176-2ARMZ-R7 is an integrated hot swap controller and power monitor IC designed to manage system power safely during board insertion and removal. It features an on-chip precision current sense amplifier, a 12-bit ADC for digital current and voltage monitoring, and an I²C interface for data access. The device controls external N-channel FETs to limit inrush current and protect against overcurrent events while reporting real-time system power data.
