AAT4900IGV-T1

Overview

The AAT4900IGV-T1 is a buffered power half-bridge gate driver manufactured by Skyworks Solutions, Inc. It operates within a supply voltage range of 2 V to 5.5 V and delivers an output voltage of 6.3 V. The device features a rise time and fall time of 5 ns, with a maximum turn-on delay of 40 ns. It consumes 4 mA of operating current and dissipates up to 526 mW of power. Designed for surface-mount installation in SOT-23-5 packages, it functions reliably across temperatures from -40°C to +85°C.

Feature Summary

• Buffered half-bridge topology for driving external MOSFETs
• Fast switching performance with 5 ns rise and fall times
• Integrated protection against under-voltage lockout conditions

Applications

• Low-side and high-side MOSFET gate driving
• DC-DC converter synchronous rectification
• Motor control bridge circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for End-of-Life notifications as the product lifecycle status indicates discontinuation. Ensure storage conditions meet moisture sensitivity level requirements before reflow soldering.

Selection Notes

Select this component when a compact half-bridge solution is required for low-voltage applications. The SOT-23-5 package suits space-constrained designs. Verify that the 5.5 V maximum supply voltage aligns with system power rails. Consider the 4 mA quiescent current for battery-operated devices requiring low standby consumption.
