ACT4921中文资料7 V Power Loss Protection Device with 6 A eFuse and Blocking FET数据手册Qorvo规格书
ACT4921规格书详情
描述 Description
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.
特性 Features
• Optimized for low voltage applications
• 8 V max input blocking voltage
• Configurable input power failure level
• Programmable up to 2.25 MHz buck operating frequency for small inductor size
• Compatible with different types of storage capacitors
• Configurable interrupts to inform host of any faults/status changes
• eFuse, boost, and buck UV/OV/OC protection
应用 Application
• Solid-State Drives
• Industrial Applications
• Hot Plug Devices
