Overview
The ADM1275-1ACPZ is a hot-swap controller and digital power monitor with PMBus interface, manufactured by Analog Devices Inc. It supports input supply voltages from 2.95 V to 20 V and operates within a temperature range of -40°C to +85°C. The device draws 5 mA of supply current and is housed in a 20-LFCSP package. It features adjustable current limiting and provides precise monitoring of voltage and current for safe insertion or removal of circuit boards from live backplanes.
Feature Summary
- Enables safe insertion and removal of circuit boards from live backplanes through controlled power sequencing.
- Integrates digital power monitoring capabilities with programmable parameters via the PMBus interface.
- Provides adjustable current limiting to protect against overcurrent conditions during hot-swap operations.
Applications
- Server and storage system backplane protection
- Telecommunications equipment power management
- Industrial control board hot-swapping
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for any updates to electrical characteristics or recommended operating conditions before final design integration.
Selection Notes
Select this component when precise digital power monitoring and PMBus communication are required alongside hot-swap functionality. Ensure the 20-LFCSP package fits the PCB layout constraints. Verify that the 20 V maximum input voltage aligns with the system power rail specifications.
Part Context
This part belongs to the ADM1275 series of hot-swap controllers designed for high-reliability applications. It complements other Analog Devices power management solutions by offering integrated monitoring and control features in a compact surface-mount package suitable for dense electronic assemblies.
Replacement Considerations
Check for official replacement notices from Analog Devices. The ADM1275-3ACPZ is a related variant within the same family but may differ in specific configuration options or packaging details. Consult the latest product change notifications for discontinuation status.
