Features include two output channels, dynamic short circuit protection and failure management.

Boasting a mean time between failures of more than two million hours, the service life of this driver is triple that of standard IGBT drivers. The optimised layout featuring unique electromagnetic shielding and integrated short-pulse suppression guarantees protection from external interference. Either way, it makes it much easier to switch the IGBTs individually when you can access their own gates and emitters directly. Why so many pins? Signal cable should be placed as far away as possible from power terminals, power cables, ground cables, DC-link capacitors and all other noise sources.

Tracks on the printed circuit board should be kept as short as possible. Loops should be avoided. In noise intensive applications, it is recommended that shielded cables or fibre optic interfaces be used to improve noise immunity.

Length of cable should be as short as possible and should not exceed three metres. Twisted pair cable should be used. Control signals low-power signal are not to be grouped with high-power signals power supply. Use signal ground and power supply ground separately. Both should be tied at one point only in most cases at the driver to avoid looping. The minimum distance between control signal cable and power cable should be 30cm and the cables should cross vertically only.

It is recommended that all cables be kept close to ground e. Use a low value capacitor 1nF between signal and power supply ground of the gate driver for differentialmode noise suppression.

The use of an recommended. With current limited line drivers, this capacitor can cause a small delay of a few ns. The capacitors have to be placed as close to the gate driver interface as possible. In conventional solutions, drivers and power modules are connected by wires that are as short and as low-inductive as possible and twisted pair.
