    • The invention is directed to a method for controlling a deceleration process of a DC motor (20), wherein the DC motor (20) is driven by a bridge driver (18) coupled to a power supply (12) intended to provide a supply voltage VDD at a power supply output (14), the method comprising the following steps: applying a deceleration PWM signal to the bridge driver (18) for decelerating the DC motor (20), and controlling the bridge driver (18) such that a motor-induced back current is reduced, if the voltage at the power supply output (14) exceeds a first voltage threshold which is higher than VDD. In accordance with the invention the method comprises the following step: if the voltage at the power supply output (14) falls below a second voltage threshold which is lower than the first voltage threshold, terminating controlling the bridge driver (18) such that the motor-induced back current is reduced. The invention is also directed to a controller (10) for controlling a deceleration process of a DC motor (20) which is driven by a bridge driver (18) coupled to a power supply (12) intended to provide a supply voltage VDD at a power supply output (14), the controller (10) comprising: means (22) for applying a deceleration PWM signal to the bridge driver for decelerating the DC motor, and means (24, 26, 28; 24, 30) for controlling the bridge driver (18) such that the motor-induced back current is reduced, if the voltage at the power supply output (14) exceeds a first voltage threshold which is higher than VDD. In accordance with the invention the means for controlling the bridge driver (18) such that the motor-induced back current is reduced are adapted to terminate controlling the bridge driver (18) such that the motor-induced back current is reduced, if the voltage at the power supply output (14) falls below a second voltage threshold which is lower than the first voltage threshold.
