AAT4610BIGV-1-T1

Overview

The AAT4610BIGV-1-T1 is a discontinued high-side power switch from Skyworks Solutions Inc., part of the ASPM family. It features a P-channel MOSFET with a maximum continuous output current of 2A and a typical on-resistance of 145 milliohms. The device operates within a load voltage range of 2.4V to 5.5V without requiring a separate supply voltage. It utilizes a non-inverting open/switch interface and is housed in an SOT-23-5 package. Integrated fault protection includes adjustable current limiting, overtemperature shutdown, and under-voltage lockout (UVLO).

Feature Summary

• Integrates a high-side P-channel MOSFET for efficient power distribution control.
• Provides comprehensive fault protection including adjustable current limiting and thermal shutdown.
• Operates without a separate supply voltage, simplifying system design.
• Features a non-inverting input interface for straightforward logic control.

Applications

• Portable electronic devices requiring protected power rails
• Battery-powered systems needing high-side switching
• General-purpose load driver applications

Procurement Notes

This component is officially discontinued and no longer manufactured by Skyworks Solutions Inc. Procurement must rely on available surplus or substitute components.
