AAT4282BIPS-3-T1C

Overview

The AAT4282BIPS-3-T1C is a high-side load switch manufactured by Skyworks Solutions Inc. It operates within a supply voltage range of 1.5 V to 5.5 V and features a typical on-resistance (Rds On) of 63 mOhms. The device supports non-inverting input control and includes slew rate controlled output for soft-start capabilities. It integrates load discharge functionality and operates reliably across an extended temperature range from -40°C to +85°C. Packaged in an 8-pin FTDFN format, it provides efficient power distribution with low quiescent current characteristics suitable for portable applications.

Feature Summary

• Slew rate controlled output minimizes inrush current during startup
• Integrated load discharge ensures rapid output voltage decay when disabled
• Non-inverting logic interface simplifies system control integration

Applications

• Portable consumer electronics power management
• Battery-powered device load switching
• Peripheral power distribution in mobile systems

Procurement Notes

Verify the exact package marking and date code against the official Skyworks datasheet before integration. Confirm that the FTDFN-8 footprint matches your PCB design guidelines. Ensure thermal dissipation requirements are met given the 63 mOhm resistance under expected load conditions. Check for any specific handling instructions related to moisture sensitivity level if storage duration exceeds factory limits.

Selection Notes

Select this component when low on-resistance and controlled turn-on speed are critical for protecting sensitive downstream loads. The non-inverting input aligns with standard logic levels, reducing gate drive complexity. Consider the 63 mOhm Rds On for efficiency calculations at maximum expected current. The integrated discharge feature eliminates external components typically required for safe shutdown, saving board space.

Part Context

This part belongs to the AAT4282 family of high-side switches designed for power distribution in compact electronic devices. It complements other Skyworks PMIC solutions by providing precise load control with minimal external component count. The FTDFN package allows for high-density PCB layouts common in modern handheld and wearable technology designs.

Replacement Considerations

Direct substitutes include AAT4282AIPS-3-T1 and AAT4282BIPS-3-T1. Verify pin compatibility and electrical parameters such as Rds On and operating voltage ranges before substitution. Ensure the replacement part maintains the same non-inverting input configuration and package dimensions.
