ADM1275-3ACPZ-R7

Overview

The ADM1275-3ACPZ-R7 is a hot swap voltage controller designed for low-voltage positive power supply applications. It integrates adjustable current limiting and power monitoring capabilities within a single channel. The device operates with an input voltage range from 2.95 V to 20 V. It features a 20-pin LFCSP surface-mount package suitable for automated assembly. The component supports an operating temperature range from -40°C to +85°C. Quiescent current consumption is specified at 5 mA. This controller provides protection against overcurrent conditions during board insertion or fault scenarios.

Feature Summary

• Integrates adjustable current limit control for precise overcurrent protection
• Includes built-in power monitoring functionality for system health tracking
• Supports hot swap operations for safe live board insertion

Applications

• Low voltage positive hot swap power distribution systems
• Industrial equipment requiring controlled power sequencing
• Telecommunications infrastructure power modules

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the -3 variant designation matches the required pinout and electrical characteristics for your design. Check manufacturer notices regarding end-of-life status as discontinuance notifications may affect long-term availability. Ensure compatibility with your PCB footprint for the 20-pin LFCSP package.

Selection Notes

Select this component for applications requiring integrated current limiting and power monitoring in a compact form factor. Consider the 20 V maximum input voltage constraint for system design. Evaluate the 5 mA quiescent current against total power budget requirements. Verify that the adjustable current limit feature meets the specific load protection thresholds needed for the target application.
