AAT4280IGU-1-T1

Overview

The AAT4280IGU-1-T1 is a high-side power switch IC manufactured by Skyworks Solutions Inc. It features a P-channel MOSFET output capable of handling up to 2.3A with a typical on-resistance of 80 milliohms. The device operates within a load voltage range of 1.81V to 5.5V and supports an input control interface. Key electrical specifications include a maximum operating time of 1 microsecond and a power dissipation rating of 714 mW. It functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Features slew rate controlled load switching to minimize inrush current and voltage droop during turn-on events.
• Includes integrated UVLO (Under Voltage Lock Out) for fault protection and reliable operation under low supply conditions.
• Provides fast load release capabilities to ensure rapid discharge of capacitive loads upon shutdown.

Applications

• Power distribution networks in portable consumer electronics
• Load switching for peripheral devices in mobile platforms
• Battery-powered equipment requiring controlled power sequencing

Procurement Notes
