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.

FEATURES
   Allows safe board insertion and removal from a live
      backplane
   Controls supply voltages from 3.15 V to 16.5 V
   Precision current sense amplifier
   Precision voltage input
   12-bit ADC for current and voltage readback
   Charge-pumped gate drive for external N-channel FET
   Adjustable analog current limit with circuit breaker
   ±3% accurate hot swap current limit level
   Fast response limits peak fault current
   Automatic retry or latch-off on current fault
   Programmable hot swap timing via TIMER pin
   Active high ON pin
   ALERTB output for overcurrent interrupt
   I2C fast mode-compliant interface (400 kHz maximum)
   10-lead MSOP

APPLICATIONS
   Power monitoring/power budgeting
