<p>The device has a center tap (MA) provided between an output stage switch (T1) and an inductive load (L) and connected with a measuring circuit (MS). A control circuit (SS) creates a measurement breaking interval by suppressing a pulse width modulation (PWM) activating interval. The control circuit monitors the voltage at the center tap with the measuring circuit within the breaking interval and compares the voltage with a reference value.</p> |
