Overview
The AAT4280AIJS-2-T1 is a high-side power load switch manufactured by Skyworks Solutions. It operates within an input voltage range of 1.5 V to 5.5 V and features a maximum on-resistance of 120 mOhms. The device provides slew rate controlled load switching with a maximum turn-on time of 1 us. It is designed for surface mount installation in an SC70JW-8 package. The component supports a single output channel and functions reliably across an ambient temperature range from -40 C to +85 C.
Feature Summary
- Slew rate controlled load switching capability
- High-side P-channel MOSFET configuration
- Integrated fault flag for over-current detection
Applications
- Load current protection in portable electronics
- Power distribution in battery-operated devices
- System power supply sequencing
Procurement Notes
Verify the End-of-Life (EOL) status before procurement, as this component may be discontinued or subject to limited availability. Confirm RoHS compliance details through official datasheets. Ensure the SC70JW-8 package dimensions match your PCB footprint requirements. Check for any product change notifications that might affect pinout or electrical characteristics.
Selection Notes
Select this component when slew rate control is required to minimize inrush currents during system startup. The 120 mOhm on-resistance suits applications with moderate load currents. Verify that the 1.5 V to 5.5 V operating voltage aligns with your system rails. Consider the SC70JW-8 package size constraints for your design layout.
Part Context
This part belongs to Skyworks' ASPM (Application Specific Power MOSFET) family. It integrates a high-side switch with control logic for efficient power management. The device is designed to replace discrete MOSFET solutions, offering a compact footprint and simplified circuit design for power distribution tasks.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Skyworks Solutions technical support for potential alternatives or cross-reference options.
