Voice Coil Motor Driver with PWM Input

The 800 series is a high performance, cost effective DC Motor Driver to implement intelligent Motion Control. The driver incorporates surface mount technology to achieve an exceptional power density.


This driver does not accept any type of feedback. It may be used in open loop applications. This module may also be used as a driver with a controller that accepts feedback and generates "PWM and direction outputs".



Features:
  • Run DC and Voice Coil Motors with PWM and Direction Control Inputs
  • 4 Amp Motor Output
  • +6 VDC to +30 VDC Power Supply
  • 0 ºC to 70 ºC Operating Temperature
  • Light: 0.36 Oz (10 gm)
  • PWM Frequency up to 40 KHz

    Pinout - Logic

    PIN Default State Description
    GND   Ground connection for logic
    PWM LOW Pulse width modulation input: a PWM signal on this pin corresponds to a PWM output on the motor outputs
    DIR FLOAT Direction input: when DIR is high current will flow from OUTA to OUTB, when it is low current will flow from OUTB to OUTA
    RESET HIGH When held low, it disables the driver

    Pinout - Power

    PIN Description
