IR4426SPBF

Gate Driver Overview

The IR4426SPBF is a dual low-side gate driver manufactured by Infineon Technologies, designed for driving IGBTs and MOSFETs. It operates within a supply voltage range of 6 V to 20 V and features an inverting logic configuration. The device provides a peak output current of 3.3 A with propagation delays of up to 160 ns. It utilizes a DSO-8 surface-mount package and supports CMOS and LSTTL logic inputs. The component is scheduled for obsolescence.

Gate Driver Feature Summary

• Dual-channel low-side gate driver topology
• Inverting input logic configuration
• High peak output current capability

Gate Driver Applications

• IGBT gate driving
• MOSFET gate driving
• Power management IC applications

Gate Driver Procurement Notes

Verify the end-of-life status before procurement, as the manufacturer has scheduled this part for discontinuation. Confirm that the DSO-8 package and inverting logic meet design requirements. Check for available substitute models from the same product family if long-term supply stability is required. Ensure compatibility with existing PCB footprints and control signal polarities.

Gate Driver Selection Notes

Select this component for non-isolated low-side switching applications requiring moderate drive strength. The inverting configuration necessitates careful consideration of input signal polarity relative to the control logic. Verify that the 6 V to 20 V supply range aligns with the system's power architecture. Consider the obsolescence timeline when planning production volumes.

Gate Driver Part Context

This part belongs to the IR(S)442X series of gate drivers from Infineon Technologies. It is specifically engineered for general-purpose power switching applications. The series includes variants with different pinouts and configurations, such as the IRS4426 which offers non-inverting logic.

Gate Driver Replacement Considerations

The IR4426STRPBF is a tape-and-reel variant of the same functional device. For non-inverting logic requirements, the IRS4426SPBF serves as a logical alternative within the same package.
