AUIRB24427STR

Gate Driver Overview

The AUIRB24427STR is a dual low-side gate driver IC designed for N-channel MOSFETs. It features non-inverting logic and operates within a supply voltage range of 6 V to 20 V, with a maximum rating of 24 V. The device provides a peak output current of 6 A per channel. Key timing parameters include rise and fall times of 33 ns, with maximum turn-on and turn-off delays of 160 ns and 150 ns respectively. It functions across an extended temperature range from -40 C to +125 C.

Gate Driver Feature Summary

• Dual independent channels for driving N-channel MOSFETs
• Non-inverting logic configuration
• High peak output current capability of 6 A
• Extended operating temperature range

Gate Driver Applications

• Power management circuits
• Industrial motor control systems
• High-current switching applications

Gate Driver Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to ensure correct package type and tape/reel specifications. Confirm RoHS compliance status and lead-free material declarations as required by project standards. Cross-reference the datasheet revision date to ensure alignment with current design constraints and manufacturing availability.

Gate Driver Selection Notes

Select this component when high current drive capability is required for N-channel MOSFETs in low-side configurations. The non-inverting logic simplifies interface with standard control signals. Ensure the application voltage does not exceed the 24 V absolute maximum rating. Consider thermal dissipation requirements given the 625 mW power dissipation limit in the SOIC-8 package.

Gate Driver Part Context

This part belongs to the IR(S)442X series of gate drivers from Infineon Technologies. It is a successor or variant within the family of dual low-side drivers, offering enhanced current drive compared to earlier iterations like the IR4427. The PG-DSO-8-9 package provides a compact solution for surface-mount assembly.

Gate Driver Replacement Considerations

The IR4427STRPBF is a related dual low-side driver within the same series but offers lower output current (1.5 A). Verify if the higher 6 A drive capability of the AUIRB24427STR is necessary for the specific load requirements before substituting.
