ACT4921QI301-T

Overview

The ACT4921QI301-T is a specialized power management IC designed for power loss protection and eFuse applications. It features an input voltage range of 2.6 V to 7 V and supports a maximum output voltage of 28 V. The device operates within a temperature range of -40°C to +105°C or 125°C depending on the specific variant documentation. It draws a supply current of 530µA and is housed in a 16-WFQFN exposed pad package, also described as 32-FCQFN (4x4) in some listings.

Feature Summary

• Provides autarch capacitor health monitoring for optimized system protection
• Highly integrated power loss protection functionality
• Supports eFuse application requirements

Applications

• Solid State Drives (SSD) power protection
• Systems requiring power loss protection
• eFuse implementations

Procurement Notes

Verify the exact operating temperature rating (+105°C vs +125°C) and package designation (16-WFQFN vs 32-FCQFN) against the manufacturer's official datasheet for the specific suffix. Ensure compatibility with the target input voltage range of 2.6 V to 7 V. Confirm that the 530µA supply current meets the system's standby power constraints.

Selection Notes

Select this component when designing systems that require robust power loss protection and capacitor health monitoring. It is suitable for applications needing an eFuse solution with low quiescent current. Ensure the design accommodates the specified input voltage window and thermal environment limits defined in the technical specifications.
