ACT85411-101SR

Overview

The ACT85411-101SR is a specialized Power Management IC (PMIC) from Qorvo, designed for enterprise-level storage systems. It integrates power management and Power Loss Protection (PLP) functions into a single chip to reduce PCB footprint and component count. The device operates within an input voltage range of 2.7 V to 14.4 V and supports an output current of 10 A. Housed in a QFN-52 package with SMD/SMT mounting style, it features humidity sensitivity compliance. This solution enables autonomous health checks, configurable power loss detection thresholds, and millisecond-level switching to backup power during outages.

Feature Summary

• Integrates PMIC and PLP functions on a single chip to minimize board space and BOM complexity
• Provides autonomous health checks and real-time monitoring of supercapacitor status
• Features configurable soft-start slope control and eFuse current limiting to prevent current surges
• Supports configuration via GPIO or I2C interfaces for flexible system integration

Applications

• Enterprise SSD power management
• Data center storage controllers
• AI server storage subsystems
• Edge computing storage nodes

Procurement Notes

Verify the specific suffix '101' against official Qorvo documentation to confirm exact pinout and configuration options, as ordering suffixes may define functional variations. Ensure compatibility with your target input voltage range of 2.7 V to 14.4 V. Confirm that the QFN-52 package dimensions align with your PCB layout constraints. Validate that the humidity sensitivity rating meets your manufacturing process requirements before assembly.

Selection Notes

Select this component when high integration of power management and data protection is required for enterprise storage. It is suitable for designs needing reduced component count and improved reliability through integrated eFuse and surge protection. Consider its I2C/GPIO configurability if dynamic adjustment of power parameters is necessary. Evaluate the QFN-52 package suitability for your thermal and spatial constraints compared to discrete solutions.

Part Context

The ACT85411 belongs to Qorvo's advanced PMIC portfolio targeting enterprise-grade applications. It addresses the growing demand for reliable power solutions in AI-driven data centers where data integrity during power events is critical. By combining traditional PMIC capabilities with dedicated PLP logic, it simplifies the design of robust storage systems that must withstand harsh operating conditions and frequent hot-plugging events.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Discrete PLP solutions or other Qorvo PMICs without integrated PLP may require significant redesign. Verify electrical compatibility and pinout differences carefully if considering alternative vendors.
