1. Description

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 unidi-

rectional 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.
