High speed and high performance motor control and lower power consumption are required for applications that include 3D printers, office equipment, banking terminals such as ATMs, cash dispensers, amusement machines, and home appliances. To meet these conflicting requirements, Toshiba has applied its original current optimization technology, AGC[1], to a new motor driver IC that achieves a large current drive (50V/5A rating).

Recent years have seen increasing demand for equipment offering higher accuracy and quieter operation. Toshiba’s new motor driver IC realizes high accuracy and low vibration by delivering 128 micro steps, realizing a much higher definition than conventional 32-step devices. It also uses SMD[2], a current adjustment function, to reduce noise and vibration effectively during motor drive by selecting the SMD configuration best suited for each motor.

Use of another Toshiba original current detection technology, ACDS[3], reduces the number of components required for driver control, contributing to lower system costs and improved flexibility in board pattern design.

Main features

  1. Reduced vibration and noise
    A high accuracy drive is realized by high-definition micro stepping with up to 128 steps, which realized much lower vibration than 32-step products[4].
  2. Support for high torque drive
    Large current drive (50V/5A rating) supports higher torque operation. Heat generation is reduced by adoption of low on resistance (0.25 Ω).
  3. High efficiency motor drive and elimination of external components.
    AGC technology prevents motor stalls and reduces power consumption, ACDS eliminates components, and ADMD[5] improves current following capability.
  4. Support for various I/F
    CLK input or serial input can be selected according to the user’s signal source. Current can be controlled directly with the serial input.
  5. Built-in error detections
    Thermal shutdown detection and overcurrent protection are incorporated. In addition, an open detection function prevents disconnection from the motor during assembly. When activated, they output error detection flags (ERR), ensuring equipment safety and highly reliable designs.

Applications

3D printers, surveillance cameras, electric actuators, home appliances (refrigerators and air-conditioners), industrial equipment (banking terminals, such as ATMs, office equipment, facsimile machines, etc.), game machines, such as slot machines, etc.
