GENERAL DESCRIPTION
The ADM1177 is an integrated hot swap controller 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
   Soft start pin for reference adjustment and programming of
      initial current ramp rate
   Active high ON pin
   I2C fast mode-compliant interface (400 kHz maximum)
   10-lead MSOP

APPLICATIONS
   Power monitoring/power budgeting
   Central office equipment
   Telecommunications and data communications equipment
   PCs/servers
