AAT4610BIGV-T1

Overview

The AAT4610BIGV-T1 is a discontinued high-side power switch IC from Skyworks Solutions, part of the ASPM series. It features a single P-channel MOSFET output capable of handling up to 2A continuous current with a typical on-resistance of 145 milliohms. The device operates within a load voltage range of 2.4V to 5.5V and utilizes a non-inverting input interface. Integrated fault protection includes adjustable current limiting, over-temperature shutdown, and under-voltage lockout (UVLO). It is housed in a compact SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates a high-side P-channel power switch for efficient load control
• Provides comprehensive fault protection including adjustable current limit and thermal shutdown
• Features low on-resistance for minimized power loss and heat generation
• Utilizes a simple non-inverting logic interface for easy system integration

Applications

• Portable electronic devices requiring protected power distribution
• Battery-powered systems needing efficient load switching
• Consumer electronics with multiple peripheral power rails
• Industrial control modules requiring robust fault protection

Procurement Notes

This component has been officially declared obsolete by the manufacturer. Verification of availability is restricted to surplus or secondary market sources. Buyers must confirm the authenticity and storage history of existing stock. Replacement components should be evaluated for pin compatibility and electrical equivalence before finalizing procurement decisions.

Selection Notes

Designers should consider the discontinuation status when selecting this part for new products. Alternative solutions must match the SOT-23-5 footprint and support the required 2A current capacity. Verify that substitute devices offer comparable on-resistance and fault protection thresholds to ensure system reliability and performance consistency across the supply chain.
