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.
