ADM1281-2ACPZ-RL

Overview

The ADM1281-2ACPZ-RL is a low-voltage hot swap controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.5 V to 20 V and features a single channel configuration. The device incorporates a 12-bit ADC for precise monitoring and utilizes I²C communication for control. It functions within an operating temperature range of -40°C to +85°C and is housed in a 32-pin LFCSP package.

Feature Summary

• Integrates a 12-bit analog-to-digital converter for real-time system monitoring
• Supports I²C communication interface for digital control and data access
• Provides comprehensive protection against overvoltage, undervoltage, and current faults

Applications

• Server power monitoring and control systems
• Telecommunications equipment power management
• Data communication infrastructure power budgeting

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm the specific suffix matches required packaging options such as reel or cut tape. Ensure compatibility with EVAL-ADM1281-AZ evaluation tools for design validation before final procurement commitment.

Selection Notes

Select this controller for applications requiring precise voltage and current monitoring via integrated ADC capabilities. Consider the 32-LFCSP package for space-constrained designs. Verify that the 4.5 V to 20 V input range aligns with the target system power rails and that I²C bus compatibility exists with the host microcontroller.

Part Context

This component belongs to the ADM1281 series of low-voltage hot swap controllers from Analog Devices. It is designed to manage power insertion into live backplanes safely. The part serves as a critical interface between the power source and the load, ensuring controlled ramp-up and fault isolation in high-reliability electronic systems.

Replacement Considerations

The ADM1278-1ACPZ-RL is identified as a discontinued predecessor. Designers should evaluate the ADM1281-1ACPZ-RL as a potential functional substitute, noting differences in channel configuration and feature sets during migration planning.
