ADM1275-1ARQZ-R7

Overview

The ADM1275-1ARQZ-R7 is a hot-swap controller manufactured by Analog Devices Inc. It supports an input voltage range of 2.95 V to 60 V and operates within a temperature range of -40°C to +125°C. The device integrates a 12-bit analog-to-digital converter (ADC) for current and voltage monitoring via the PMBus interface. It is housed in a 20-pin QSOP package.

Feature Summary

• Enables safe insertion and removal of circuit boards from live backplanes
• Integrates a 12-bit ADC for precise power monitoring
• Provides digital control and feedback through the PMBus interface

Applications

• Server blade insertion systems
• Telecommunications equipment hot-plug modules
• Industrial control board replacement

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the 20-pin QSOP package matches your PCB footprint requirements. Ensure compatibility with existing PMBus host controllers for proper communication. Check for any recent lifecycle notifications regarding availability status.

Selection Notes

Select this component when high-voltage hot-swap protection is required alongside digital power management capabilities. The integrated ADC eliminates the need for external sensing circuits. Verify that the system design can accommodate the 20-pin QSOP form factor and supports the necessary I2C/PMBus protocol for configuration.

Part Context

This part belongs to the ADM1275 series of hot-swap controllers. It is designed for applications requiring robust power sequencing and protection during board insertion. The integration of digital power features distinguishes it from basic analog-only controllers in the same category.

Replacement Considerations

Check for ADM1275 variants with different pin counts or interfaces. Verify if ADM1275-2ARQZ or other suffixes offer compatible functionality for direct substitution.
