• Supports high-voltage offset environments up to 600V
• Features dedicated HIN and LIN input channels

Applications

• IGBT gate driving
• MOSFET gate driving
• Power inverter circuits

Procurement Notes

Verify the exact suffix (e.g., -X) against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the 600V offset rating aligns with your system's common-mode noise requirements before finalizing procurement.

Selection Notes

Select this component when independent control of high-side and low-side switches is required in high-voltage applications. Ensure the 290mA source and 600mA sink currents are sufficient for the target IGBT or MOSFET gate charge requirements within the desired switching frequency.

Part Context

This part belongs to Littelfuse's series of high-side and low-side drivers designed for power electronics. It serves as a critical interface between low-voltage logic controllers and high-power switching devices, enabling efficient energy transfer in motor drives and power supplies.

Replacement Considerations

Check for direct pin-to-pin replacements with similar offset voltages and drive currents. Verify compatibility with existing PCB footprints and thermal management solutions when substituting.
