IXDF404SI-16

Overview

The IXDF404SI-16 is a dual low-side ultrafast MOSFET gate driver manufactured by IXYS. It features two independent outputs, each capable of sourcing and sinking 4A of peak current. The device operates within a supply voltage range of 4.5V to 35V and supports both inverting and non-inverting logic configurations. It utilizes a 16-SOIC package with a 7.50mm width and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Dual-channel architecture providing independent control for two power switches
• High peak output current capability of 4A per channel for rapid switching
• Ultrafast propagation characteristics suitable for high-frequency applications
• Flexible logic input compatibility with standard CMOS and TTL levels

Applications

• Motor control systems requiring precise IGBT or MOSFET driving
• Power management circuits utilizing low-side switching topologies
• Inverter designs for AC drives and industrial automation
• DC-DC converter stages needing fast transient response

Procurement Notes

Verify the specific suffix '-16' to confirm the 16-SOIC package variant, as other suffixes may indicate different packaging or pinout configurations. Ensure the application circuit matches the low-side driver topology, as this component is not designed for high-side or half-bridge floating applications without additional bootstrap circuitry. Confirm voltage ratings align with the target power device gate requirements.

Selection Notes

Select this component when dual low-side isolation is required with high peak drive current. It is suitable for applications demanding fast switching speeds to minimize conduction losses. Consider the 16-SOIC package for PCB layout constraints if space allows for its wider footprint compared to smaller packages. Verify that the control logic voltage levels are compatible with the 4.5V minimum supply requirement.

Part Context

This part belongs to the IXD_404 series of dual MOSFET drivers from IXYS Integrated Circuits. The series is characterized by high-speed performance and robust output stages designed for driving various power semiconductor devices including N-Channel and P-Channel MOSFETs as well as IGBTs. The family offers flexibility through multiple package options and logic configurations.

Replacement Considerations

The IXDI404SI-16 serves as a direct functional substitute within the same product family, offering identical electrical specifications but potentially differing in internal protection features or logic polarity. Cross-reference datasheets to ensure pinout compatibility and verify that any alternative components meet the 4A peak current and 35V supply limits.
