IGD616

MEDIUM/HIGH-POWER SINGLE CHANNEL SCALE DRIVER CORE

A successor to the IGD608 and IGD615 gate driver cores

Highly approved SCALE technology

For 1200V and 1700V IGBTs

Short Description

The IGD616 is a highly-integrated single IGBT driver core based on CONCEPT's proprietary SCALE technology which has been established on the market as an industrial standard since 1999.

The IGD616 has been developed for direct replacement of IGD608 and IGD615. It features a dedicated set of compatible items to ease seamless transition in existing designs. Its drive power and performance exceed prior specifications such that now one single driver core IGD616 will cover the range of both IGD608 and IGD615 at a superior reliability level.

The driver core is optimized to match various IGBTs and applications from 100A / 1200V to 1000A / 1700V and beyond.

Compatibility to IGD608 / IGD615 Gate Drivers

The IGD616 is 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.

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 22ms. 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.
