AAT4616AIPU-1-T1

Overview

The AAT4616AIPU-1-T1 is a single-channel power distribution switch manufactured by Skyworks Solutions. It integrates a P-channel MOSFET with an active-high control interface, operating within a supply voltage range of 2.4 V to 5.5 V. The device supports a maximum output current of 2 A and features a typical on-resistance of 130 mOhms, with a maximum rating of 230 mOhms. Key protection mechanisms include adjustable current limiting, over-temperature shutdown, reverse current blocking, and UVLO. It provides a fault flag status indicator and operates reliably across a temperature range of -40°C to +85°C in a compact 6-TDFN package.

Feature Summary

• Integrates high-side P-channel MOSFET with active-high logic control for simplified interfacing
• Provides comprehensive fault protection including adjustable current limit, thermal shutdown, and reverse current blocking
• Includes a dedicated fault flag output to signal system anomalies such as over-current or over-temperature events

Applications

• Power distribution in portable consumer electronics
• Load switching in battery-powered devices
• Protection circuits for peripheral interfaces

Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturer channels. Ensure that any sourced units are verified for authenticity and storage history due to the end-of-life status. Cross-reference part numbers may be required for new designs.

Selection Notes

Select this component only if legacy compatibility is required, as it is obsolete. For new designs, consider alternatives with similar electrical characteristics, such as the MIC2095-2YMT-TR. Evaluate the trade-off between the specific 130 mOhm on-resistance and the active-high control requirement against available modern equivalents. Verify that the 2 A current capability and 5.5 V maximum voltage align with the target application's load profile.

Part Context

The AAT4616 series belongs to Skyworks' portfolio of smart switches designed for power management applications. This specific variant, AAT4616AIPU-1-T1, distinguishes itself through its active-high enable pin configuration, contrasting with other family members that may utilize active-low controls. It is part of the broader ASPM product line, emphasizing integrated protection features within a small form factor suitable for space-constrained mobile and industrial systems.

Replacement Considerations

The MIC2095-2YMT-TR from Microchip Technology is documented as a similar replacement option.
