ATA6830 - INTELLIGENT STEPPER MOTOR DRIVER

General 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 unidirectional serial single-wire bus.

Key Features

  • 2-Phase 1 A Stepping Motor Driver Compensated Half Step Operation Chopper Current Control Unidirectional Single Wire Bus Interface with Error Feedback Intelligent Travel Operation Control Referencing by Extending or Retracting.
