Overview
The ADM1177-2ARMZ-R7 is a hot swap voltage controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 3.15 V to 16.5 V and features a single channel configuration. The device draws a typical operating supply current of 1.7 mA. It supports surface mount installation in a 10-MSOP package and functions reliably across an extended temperature range from -40°C to +85°C.
Feature Summary
- Integrated on-pin latch-off functionality for immediate shutdown during fault conditions
- Supports automatic retry mechanisms following fault clearance
- Includes I2C interface capability for digital control and monitoring
Applications
- Hot swap circuit protection in server backplanes
- Power management in industrial communication equipment
- System board insertion protection for modular hardware
Procurement Notes
Verify component authenticity through authorized channels due to limited availability status. Confirm the specific suffix designation matches design requirements, as variations may exist within the product line. Ensure compatibility with existing PCB footprints and thermal management strategies before finalizing procurement decisions.
Selection Notes
Select this component when precise voltage regulation and controlled power-up sequencing are required for sensitive loads. The integrated fault protection features simplify design complexity compared to discrete solutions. Consider the MSOP package constraints regarding thermal dissipation and pin pitch during layout planning.
Part Context
This part belongs to the ADM1177 series of hot swap controllers designed for robust power distribution applications. It complements other PMIC offerings from Analog Devices by providing specialized protection against overcurrent and short-circuit events during module insertion or system faults.
Replacement Considerations
The ADM1177-1ARMZ-R7 serves as a verified alternative within the same family, offering identical core functionality but potentially differing in specific ordering suffixes or packaging configurations.
