AAT4618IGV-0.5-1-T1

Overview

The AAT4618IGV-0.5-1-T1 is a single-channel power distribution switch manufactured by Skyworks Solutions Inc., belonging to the ASPM series. It features a P-channel MOSFET output configured for high-side switching with an open/switch interface. The device supports load voltages between 2.4V and 5.5V, operating within a temperature range of -40°C to +85°C. Key electrical specifications include a typical on-resistance of 125 milliohms and integrated fault protection mechanisms such as fixed current limiting, overtemperature shutdown, and under-voltage lockout (UVLO). It is housed in a compact SOT-23-5 surface-mount package.

Feature Summary

Integrates a P-channel MOSFET for efficient high-side power distribution control
Provides comprehensive fault protection including fixed current limiting, thermal shutdown, and under-voltage lockout
Includes a status flag feature for monitoring operational state

Applications

Power management circuits requiring single-channel load switching
Portable electronic devices utilizing 2.4V to 5.5V supply rails
Systems needing compact high-side switch solutions with integrated protection

Procurement Notes

This component has been officially discontinued and is no longer in manufacturing. Verification of availability should focus on identifying qualified replacement parts rather than sourcing the original item. Buyers must confirm that any substitute component meets the required voltage, current, and package specifications to ensure system compatibility.

Selection Notes

Designers should evaluate alternative components due to the discontinuation of this part. Selection criteria must prioritize matching the SOT-23-5 footprint, 2.4V to 5.5V operating range, and P-channel configuration. Ensure the replacement offers comparable on-resistance and fault protection features to maintain circuit integrity and safety standards.

Part Context

The AAT4618 belongs to Skyworks' ASPM series of power switches, designed for space-constrained applications. This specific variant utilizes the IGV suffix indicating the SOT-23-5 package and T1 denotes reel packaging. As a PMIC component, it serves as a fundamental building block for power distribution networks in consumer electronics and industrial systems.
