IXDF404PI

Overview

The IXDF404PI is a dual low-side ultrafast MOSFET gate driver manufactured by IXYS Integrated Circuits. It features two independent drivers in an 8-pin DIP package, delivering a peak output current of 4 A per channel. The device operates with a supply voltage range of 4.5 V to 35 V and accepts CMOS or TTL logic inputs. Key timing parameters include a rise time of 9 ns and a fall time of 8 ns. It supports both inverting and non-inverting configurations and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Dual-channel architecture providing independent control for two low-side switches
• Ultrafast switching performance with nanosecond-level rise and fall times
• Flexible logic compatibility supporting standard CMOS and TTL input signals
• Configurable signal inversion allowing selection between inverting and non-inverting modes

Applications

• High-frequency DC-DC converter topologies requiring fast switching transitions
• Motor drive circuits utilizing low-side MOSFET control
• Inverter systems needing precise gate drive timing
• Power supply designs employing isolated or non-isolated low-side driving

Procurement Notes

Verify component authenticity through authorized IXYS distributors due to obsolete lifecycle status. Confirm package integrity as the DIP-8 form factor may involve older manufacturing batches. Ensure compliance with RoHS directives if required by specific project standards. Cross-reference datasheet revisions to confirm pinout consistency before integration into new designs.

Selection Notes

Select this component when dual low-side driving with high speed is required in a through-hole package. Compare against the IXDI404SI for surface-mount alternatives or the IXDN604PI for active inventory options. Evaluate thermal management requirements as the DIP-8 package offers limited heat dissipation compared to larger footprints. Verify that the 4 A peak current meets the gate charge demands of the target MOSFETs at the intended switching frequency.

Part Context

The IXDF404PI belongs to the IXD_404 series of ultrafast MOSFET drivers from IXYS. This family focuses on low-side applications where rapid turn-on and turn-off capabilities are critical for efficiency. The device complements higher-current variants like the IXDN614PI and serves as a legacy alternative to newer generations such as the IXDI series.

Replacement Considerations

The IXDI404SI is a documented substitute offering identical electrical specifications in a surface-mount SOIC-CT-8 package. Designers must account for footprint changes and reflow soldering requirements when transitioning from the DIP-8 IXDF404PI to the SMD IXDI404SI.
