IXDF404SIA

Overview

The IXDF404SIA is a dual low-side ultrafast MOSFET driver manufactured by IXYS. It features two independent drivers with 4 A peak source and sink output currents, designed for high-speed switching applications. The device operates on a supply voltage range of 4.5 V to 20 V and accepts CMOS or TTL compatible logic inputs. Key electrical parameters include a typical propagation delay of 36 ns, rise time of 18 ns, and fall time of 17 ns. It functions within an operating temperature range of -55°C to +125°C and is housed in an 8-pin SOIC package.

Feature Summary

• Dual channel configuration providing independent control for two low-side switches
• Ultrafast switching capability with 4 A peak drive current for rapid MOSFET transitions
• Compatible with standard CMOS and TTL logic input levels

Applications

• Brushless DC motor drives in home appliances and power tools
• Industrial motor control systems including AC and servo drives
• High-frequency power supply topologies requiring fast switching

Procurement Notes

Verify the specific suffix 'A' against the manufacturer datasheet to confirm pinout and functional equivalence, as suffixes often denote tape-and-reel packaging or specific temperature grades. Confirm availability status as distribution channels may list obsolete or end-of-life inventory. Ensure the sourcing document explicitly identifies the component as the IXDF404SIA variant rather than the standard IXDI series.

Selection Notes

Select this component when driving dual low-side MOSFETs requiring high peak current and minimal propagation delay. The 8-pin SOIC package suits surface-mount designs with limited board space. Verify that the application logic levels match the CMOS/TTL input requirements and that the supply voltage remains within the 4.5 V to 20 V operational window for reliable performance.

Part Context

This component belongs to the IXYS IXD/IXDF series of gate drivers, which are engineered for efficient power conversion and motor control. The series utilizes IXYS silicon technology to provide robust isolation and fast switching speeds. These drivers are integral to modern power electronics, enabling precise control of power semiconductors in demanding industrial and consumer environments.

Replacement Considerations

The IXDI404SI is a documented substitute part number from the same manufacturer. Verify if the 'I' versus 'F' designation implies differences in internal circuitry or pin compatibility before substitution.
