New automotive bipolar stepper motor driver IC or dual DC motor driver IC available now

27-10-2017 | Allegro | Automotive Technologies

Allegro MicroSystems has introduced a new automotive bipolar stepper motor driver IC or dual DC motor driver IC that is designed for PWM control of low-voltage stepper motors and dual or single high current DC motors. The device is capable of output currents up to 1A per channel and operating voltages from 3.5V to 15V. Key applications include: Heads-up-Display (HUD) – mirror positioning and dust cover, navigation – screen lift, driver attention monitor – camera movement or focus, and steering wheel feedback – vibration alert.



The device is an automotive-grade device and has been tested across extended temperature and voltage ranges to ensure compliance in automotive or industrial applications. It has an internal fixed off-time PWM timer that sets a peak current based on the selection of a current sense resistor. An output fault flag is provided that notifies the user of a TSD or overcurrent protection event.
