ADM1075-2ACPZ-RL7

Overview

The ADM1075-2ACPZ-RL7 is a hot swap controller and digital power monitor manufactured by Analog Devices Inc. It supports -48V systems and features a PMBus interface for communication. The device operates within an ambient temperature range of -40°C to +85°C and is housed in a 28-pin LFCSP-WQ (5x5) package.

Feature Summary

• Integrates hot swap control with digital power monitoring capabilities
• Provides programmable current limit and soft-start functionality
• Includes overvoltage protection and fault reporting via PMBus

Applications

• -48V telecom infrastructure power distribution
• Industrial equipment power management
• Server and storage system hot swap backplanes

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when ordering. Confirm the 28-pin LFCSP-WQ footprint matches your PCB layout. Ensure compatibility with -48V input rails and PMBus protocol requirements for your system design before procurement.

Selection Notes

Select this component for applications requiring precise current limiting and power monitoring in -48V environments. The integrated PMBus interface allows for detailed telemetry and configuration. Consider the thermal performance of the 5x5mm package for your enclosure constraints.

Part Context

This part belongs to Analog Devices' hot swap controller family designed for robust power distribution. It combines analog control loops with digital monitoring, offering a compact solution for protecting sensitive loads during insertion or fault conditions in high-reliability systems.

Replacement Considerations

Check for ADM1075 variants without the RL7 suffix if tape-and-reel packaging is not required. Verify pinout compatibility with existing designs if substituting with other hot swap controllers from different manufacturers.
