IHD 260/660
Preliminary Data Sheet
Compatibility to IHD 215/280/680 Gate Drivers
The IHDx60 are available with different options covering a dedicated set of compatible
items. In this data sheet, the text referring to critical compatible items is underlined.
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.
For a summary, refer to the Ordering Information section on the last page.
