Abstract:
A motordriver for controlling a brushless DC motor, comprises: an output driver for controlling phase commutation of a power stage; the motordriver can be powered in a pulsed way having a PWM ON and OFF period; a position module for monitoring a position and/or speed of a rotor; at least a part of the position module remains active during the PWM OFF period; a power module configured for powering the active part during the PWM OFF period, comprising an energy storage medium and a blocking module configured such that during the PWM ON period the energy storage medium can be charged by the power supply, and such that the blocking module can block current flowing back to the power supply and block current flowing from the energy storage medium to the motor during the PWM OFF period.

Claim (Index 3):
A motordriver according to  claim 1 , the motordriver comprising a power adjusting module configured for obtaining a back EMF indicative signal of the motor and wherein the output driver is adapted for reducing the amount of the pulsed power that is driving the motor and/or for reducing peak currents in the motor, by reducing a PWM duty cycle of the motordriver and/or by reducing a gate voltage of at least one driving transistor in the power stage, based on the back EMF indicative signal.
