*Note: Toshiba’s proprietary technology

  • AGC: Active Gain Control
    Stepping motor drive technology that automatically optimizes motor drive current in real time according to the load torque
  • ACDS: Advanced Current Detection System
    Technology which will not require external sense resistor and monitors the motor current within the device for constant current control
  • ADMD: Advanced Dynamic Mixed Decay
    Mixed-decay technology that monitors the decay current within the IC, and optimizes the decay ratio between Fast Decay and Slow Decay modes, which enables a more broad range of motor rotation speed/frequency
