Model Number: ACT4921

Power Loss Protection Device from Qorvo

7 V Power Loss Protection Device with 6 A eFuse and Blocking FET

Status: Standard | Data Sheet:

| RoHS Compliance: Rohs Compliant

Overview

Qorvo’s ACT4921 device is a highly integrated power loss protection IC that provides autarch capacitor health monitoring for optimized system protection. A built-in boost converter enables high voltage energy storage to minimize the storage capacitor size requirements. The built-in buck converter with integrates FETs regulates the storage voltage to the system voltage and also provides hot swap capability and inrush current control.

The product is very flexible and can easily be configured and monitored with I2C and external components.

ACT4921 is available in the thermal enhanced QFN 4×4 32 pin package.
