IHD260NC1

Gate Driver Overview

The IHD260NC1 is a highly integrated dual IGBT driver core based on CONCEPT’s SCALE-1 technology, manufactured by Power Integrations. It features a non-inverting input configuration and utilizes an optocoupler for secondary-side fault signal transfer to the primary side with a typical delay of 20μs. The device includes a command blocking time of 25ms to maintain the off-state during faults. Designed for industrial and traction applications, it supports IGBTs ranging from 25 A to 450 A and voltages from 1200 V to 1700 V.

Gate Driver Feature Summary

• Integrates dual IGBT driver cores using SCALE-1 technology for optimized performance and reliability
• Features non-inverting input logic selection via Option N configuration
• Utilizes optocoupler interface for secondary-side fault signal transfer with approximately 20μs delay
• Includes fixed command blocking time of 25ms to ensure safe off-state maintenance

Gate Driver Applications

• Half-bridge control of 1700 V / 75 A IGBTs at switching frequencies up to 100 kHz
• Industrial drive systems requiring high-reliability gate driving
• Traction applications utilizing IGBT modules within specified voltage and current ranges

Gate Driver Procurement Notes

Verify that the specific suffix NC1 corresponds to the non-inverting input option and optocoupler fault feedback variant. Confirm package type and thermal characteristics match the target PCB layout. Ensure compatibility with the intended IGBT module voltage ratings and current requirements before integration into the design.

Gate Driver Selection Notes

Select this component when non-inverting logic control is required alongside isolated fault feedback. The optocoupler interface reduces initial creepage distance compared to transformer-based options. Consider the fixed 25ms command blocking time for system recovery timing. This driver is suitable for replacing older IHD 215/280/680 models where direct replacement and simplified input logic are preferred.

Gate Driver Part Context

The IHD260NC1 belongs to the IHD x60 series developed by CONCEPT, now part of Power Integrations. These drivers were created to cover application ranges previously served by the IHD 215, IHD 280, and IHD 680 families. The series establishes SCALE-1 technology as an industrial standard since 1999, focusing on combining optimum performance with competitive pricing for robust power switching applications.

Gate Driver Replacement Considerations

Direct replacements include IHD 215, IHD 280, and IHD 680 drivers. Note that input inversion methods differ; IN+ and IN- inputs cannot be interchanged to invert logic in the IHDx60 series as was possible in previous generations. Command blocking time is fixed at 25ms and is not user-adjustable.
