Analog Devices ADM1177 Manuals

The ADM1177 is a hot swap controller and digital power monitor with soft start pin from Analog Devices. It allows safe board insertion and removal from a live backplane, and controls supply voltages from 3.15 V to 16.5 V. The device also has precision current sense amplifier, precision voltage input, 12-bit ADC for current and voltage readback, charge pumped gate drive, 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) and 10-lead MSOP.

ADM1177 is a hot-swap controller and digital power monitor with soft start pin from Analog Devices. It has a maximum voltage of 16.5V, 12-bit ADC and current and voltage readback functions. It is used in power monitoring/power budgeting, central office equipment, telecommunications and data etc.

This document describes the features and characteristics of the ADM1177 hot swap controller and digital power monitor, which allows safe board insertion and removal from a live backplane.
