IHD260, IHD660

LOW/MEDIUM-POWER DUAL SCALE DRIVER CORE

A successor to the IHD 215/280/680 dual-gate driver cores

Highly approved SCALE technology

For 1200V and 1700V IGBTs

Short Description

The IHD 260 and IHD 660 (short IHDx60) are highly-integrated dual IGBT driver cores based on CONCEPT's proprietary SCALE technology which has been established on the market as an industrial standard since 1999.

As most customers apply the IHD 215, IHD 280 and IHD 680 drivers in a similar way, the IHDx60 covers a dedicated set of compatible items to give the benefits of optimum performance, optimum reliability and a competitive price.

The driver cores are optimized to match various IGBTs and applications from 25A to 450A and 1200V to 1700V.

Typical applications include half-bridge control of 1700V/75A IGBTs at switching frequencies up to 100kHz and 1700V/450A IGBTs at switching frequencies up to 18.5kHz for the IHD660 version.

Compatibility to IHD 215/280/680 Gate Drivers

The IHDx60 are available with different options covering a dedicated set of compatible items.

Option N and Option I select between non-inverting and inverting inputs respectively. It is no longer possible to interchange the IN+ and IN- inputs to invert the logic as could be done with IHD 215/280/680.
On the secondary side, any fault state is extended by a period known as the command blocking time. During this time, the driver is kept in the off-state. The command blocking time is set at the factory to a nominal value of 25ms. Other values upon request. It is no longer possible for the application to adjust the blocking time.

For option T, the signal transformer interface is used to transfer the secondary fault signal to the primary side. This transfer may be performed at each change in the command signal, but only during the blocking time. For option C, an optocoupler is used to transfer the secondary-side fault state to the primary side within a delay of less than several microseconds. The initial creepage distance and the maximum operating voltage are reduced by the optocoupler.

Reliability

SCALE drivers have been established on the market as an industrial standard since 1999. The driver have been tried and tested within hundreds of thousands of industrial and traction applications. The calculated MTBF according to MIL Hdbk 217F is 10 million hours at 40ºC. According to field data, the actual reliability is even higher.
