IRMD22141SS
The SHU, SHV and SHW are sense pins connected as close as possible to the shunt resistors terminals
to reduce the parasitic effects of the traces.
High power signal connector
There are two connectors dedicated to each power signal (DC+, U, V, W and DC-). Each single
connector has 30 Ampere of maximal nominal dc current. DCbus traces are both on top and on one of
the internal layers of the PC board in order to reduce power dissipation. Connectors, DC-bus, phase and
ground wires can be soldered directly on board using the corresponding pads located under the power
connectors (to be removed).
Connecting the power module
The board is fully compatible with the ECONO2-6PACK power module. The following table shows the
module pin-out.
