    TB67S279FTG
    Toshiba BiCD process integrated circuit silicon monolithic TB67S279FTG
    Active Gain Control Clock-in control Bipolar stepping motor driver
    The TB67S279FTG is a clock-in controlled bipolar stepping
    motor driver with a built-in Active Gain Control architecture.
    The TB67S279FTG also has an internal current feedback
    control (ACDS) which enables the driver to control the motor
    current without using a sense resistor.
    Using the BiCD process, the TB67S279FTG is rated at 50 V,
    2.0 A.
