IHD660

Gate Driver Overview

The IHD660 is a highly integrated dual IGBT driver core based on SCALE-1 technology, designed for industrial and traction applications. It supports IGBTs from 25 A to 450 A and voltages up to 1700 V. Typical use includes half-bridge control of 1700 V / 450 A IGBTs at switching frequencies up to 18.5 kHz. The device offers direct replacement compatibility with legacy IHD 215/280/680 drivers while providing optimized performance and reliability.

Gate Driver Feature Summary

• Dual IGBT driver core utilizing proprietary SCALE-1 technology for high reliability
• Optimized for IGBT currents ranging from 25 A to 450 A and voltages up to 1700 V
• Direct replacement compatibility with previous generation IHD 215, IHD 280, and IHD 680 drivers
• Integrated command blocking time to extend fault state duration

Gate Driver Applications

• Half-bridge control of 1700 V / 450 A IGBTs
• Industrial motor drives and converters
• Traction applications requiring high reliability

Gate Driver Procurement Notes

Verify the specific option suffix (N, I, T, or C) required for your application logic inversion and fault signal transfer method. Option N provides non-inverting input, while Option I provides inverting input. Options T and C differ in how the secondary-side fault state is transferred to the primary side. Confirm that the fixed nominal command blocking time of 25 ms aligns with your system's safety requirements, as user-adjustable values are no longer available.

Gate Driver Selection Notes

Select the IHD660 when replacing existing IHD 215, IHD 280, or IHD 680 drivers to maintain pin compatibility while benefiting from updated SCALE-1 technology. Choose Option N for non-inverting logic or Option I for inverting logic inputs. For fault signaling, select Option T if using a signal transformer interface or Option C if an optocoupler-based transfer is preferred to reduce creepage distance. Ensure the target IGBT specifications fall within the 25 A to 450 A current range and 1700 V voltage limit.

Gate Driver Part Context

The IHD660 belongs to the IHD x60 series of dual IGBT driver cores developed by CONCEPT. This series was created to cover the same application range as the established IHD 215, IHD 280, and IHD 680 drivers. It combines optimum performance, reliability, and competitive pricing, serving as a modernized alternative within the SCALE-1 technology family for high-power converter topologies.

Gate Driver Replacement Considerations

The IHD660 serves as a direct replacement for the IHD 215, IHD 280, and IHD 680 gate drivers. Users must note that input inversion can no longer be achieved by swapping IN+ and IN- pins; a specific option suffix must be selected during ordering. Additionally, the command blocking time is fixed at a nominal 25 ms and cannot be adjusted by the user.
