AAT4616AIPU-T1

Overview

The AAT4616AIPU-T1 is a discontinued single-channel P-channel power distribution switch manufactured by Skyworks Solutions Inc. It operates within a load voltage range of 2.4V to 5.5V and supports a maximum output current of 2A. The device features an active-low control interface with a typical on-resistance of 130 milliohms and a maximum of 230 milliohms. Key electrical parameters include a maximum on-time of 7 microseconds and off-time of 10 microseconds, with a power dissipation rating of 1.18W. It functions in high-side configurations across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates comprehensive fault protection mechanisms including adjustable current limiting, thermal shutdown, reverse current blocking, and under-voltage lockout.
• Provides status flag indication for monitoring operational state and fault conditions without requiring additional external components.
• Utilizes a compact 6-terminal TDFN surface-mount package designed for efficient thermal management and space-constrained layouts.

Applications

• Power distribution networks in portable consumer electronics
• Load switching for peripheral devices in mobile platforms
• Battery-powered system power management

Procurement Notes

This component has been officially discontinued and is no longer in production. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer supply. Engineers must confirm the specific lot date code and physical condition when sourcing from non-authorized distributors. Replacement qualification is required before integration into new designs due to the end-of-life status.

Selection Notes

Designers should evaluate the 2A current capacity and 130 milliohm on-resistance against target load requirements. The active-low control logic must align with the host controller's output signals. Thermal performance needs assessment based on the 1.18W dissipation limit and ambient operating conditions. The absence of a driver voltage supply simplifies board layout but requires careful attention to gate drive levels relative to the source potential.

Part Context

The AAT4616 series belongs to Skyworks' portfolio of power distribution switches aimed at portable applications. This specific variant utilizes a P-channel MOSFET architecture controlled via an active-low input. The family is characterized by low on-resistance and integrated protection features suitable for managing power rails in battery-operated devices where efficiency and safety are critical design constraints.

Replacement Considerations

MIC2095-2YMT-TR is identified as a similar replacement option available from Microchip Technology.

FAQ

What is the control logic polarity for the AAT4616AIPU-T1?

The device uses an active-low control interface, meaning the switch turns on when the control pin is driven low.

Does the AAT4616AIPU-T1 require an external supply voltage?

No, the device does not require a separate Vcc or Vdd supply voltage; it is powered directly through the load path.
