Beschreibung
Zusammenfassung:	An inverter power module for driving an electric motor comprising a plurality of motor drive power switches having at least one output for driving the motor, a driver integrated circuit for driving the plurality of motor drive power switches, the plurality of switches comprising at least two power switches arranged in a half bridge configuration adapted to be connected between rails of a supply bus, with a common connection between the switches serving as an output for driving the motor, the switches comprising a high side switch and a low side switch, the low side switch being connected to an external terminal of the module adapted to be connected through a sensing element to the lower potential supply bus rail, whereby a motor current can be monitored at the external connection.
