GENERAL DESCRIPTION

The ADM1176 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

Active high ON pin

I2C fast mode-compliant interface (400 kHz maximum)

2 address pins allow 16 devices on the same bus

10-lead MSOP
