Two chopper-controlled H-bridges serve as the stepping motor driver. The circuit receives the commands to control the stepping motor by means of a unidirectional serial single-wire bus. An integrated process control independently moves the stepping motor into the new desired position. This allows it to be automatically accelerated and slowed down. The stepping motor is operated in compensated half-step operation. The maximum clock frequency at which the stepping motor is operated depends on the supply voltage, the chip temperature, the operating mode, and position difference.

The circuit serves to control a stepping motor for dynamic headlamp beam adjustment in automobiles. Two chopper-controlled H-bridges serve as the stepping motor driver. The circuit receives the commands to control the stepping motor by means of a unidirectional serial single-wire bus.

An integrated process control independently moves the stepping motor into the new desired position. This allows it to be automatically accelerated and slowed down. The stepping motor is operated in compensated half-step operation. The maximum clock frequency at which the stepping motor is operated depends on the supply voltage, the chip temperature, the operating mode, and position difference.
