The ADM1177-2ARMZ-R7 is an integrated hot swap controller and digital power monitor designed by Analog Devices. It allows for safe insertion and removal of boards from live backplanes, controlling supply voltages ranging from 3.15V to 16.5V.
Key features include a 12-bit analog-to-digital converter (ADC) for current and voltage readback, communicated via an I2C interface. It offers an adjustable analog current limit with circuit breaker functionality and a ±3% accurate hot swap current limit level. The device provides fast response to limit peak fault current and supports automatic retry or latch-off on current faults.
This controller utilizes a charge-pump gate drive for an external N-channel FET and includes a soft-start pin for programming the initial current ramp rate. It operates within a temperature range of -40°C to 85°C.
The ADM1177-2ARMZ-R7 is available in a 10-MSOP package and is suitable for surface mount applications. Its primary applications include power monitoring and budgeting in telecommunications, data communications equipment, and PCs/servers.
