PT62SCMD12 Datasheet, PDF (9/12 Pages) Cree, Inc – Dual 1200V SIC MOSFET driver

4. Application notes
4.1. Input connection.
Connector
For the input connector (X10) a boxed header from Wurth is applied (612 008 217 21), a possible
mating wire connector is for example the 71600-608LF from FCI.
Wiring
For increasing the immunity of the PWM input signals the driver is equipped with differential inputs.
For reaching maximum performance the differential pairs should be physically kept close to each
other by using for example a flat cable with twisted differential pairs.
Although the differential concept already gives additional immunity it is still recommended to keep
the PWM signal lines away from conductors carrying large currents. Shielding of the wires will
increase the immunity further.
4.2. Input power.
The ramp-up of the supply voltage during start-up should be smooth and no dips should occur.

4.3. Disabling OCP
If it, for any reason, is desired to disable the OCP then this can be achieved by interconnecting:
 X31 with X33 and
 X22 with X23
Note that when X23 and/or X33 are not connected the driver will always enter its error stated when
PWM is applied.
