Abstract

A device for actuating and/or monitoring a brushless DC motor, preferably for safety-relevant applications, preferably while operating or controlling a vehicle or components of a vehicle and a method for reliably checking the functional capability of the device are provided. The device can be actuated by a motor control unit by using a control signal for actuating and/or monitoring a brushless direct current motor by using a converter circuit includes a switching-off apparatus, a driver circuit which acts on the converter circuit and a testable diagnosis unit for monitoring the device and/or the converter circuit and/or the brushless direct current motor. The switching-off apparatus acts on the driver circuit. The testable diagnosis unit can be tested for a malfunction by using a testing command transmitted by the motor control unit.
