Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched “TB9120AFTG,” a constant-current 2-phase stepping motor driver for automotive applications. The new IC outputs a sine-wave current using only a simple clock input interface, with no need for an advanced functional MCU or dedicated software.
TB9120AFTG was developed as a successor to TB9120FTG, introduced in 2019 as Toshiba’s first automotive stepping motor driver, and provides improved noise resistance.

TB9120AFTG incorporates DMOS FETs with low on-resistance (upper + lower = 0.8Ω (typ.)), which achieve a maximum current of 1.5A[1]. Both the DMOS FETs and the controller that generates micro-stepping sine waves (supporting up to 1/32 steps) are housed in a small QFN type package (6.0 mmx6.0 mm).
The new IC delivers an operating temperature range of -40 to 125?, and meets AEC-Q100, a certified standard for electronic components for automotive applications.
It is suited to a wide range of automotive general applications using stepping motors, such as adjustment of the projection position of heads-up displays, and in the expansion valves of refrigerant circuits.

Key features

  • General multipurpose specifications, especially for automotive applications
    - DMOS FETs with low on-resistance (upper + lower = 0.8Ω (typ.)), which achieve a maximum current of 1.5 A.
    - Built-in error detections with warning signal output function: Over-current detection, thermal shutdown, and load open.
    - Housed in a wettable flank VQFN package (6mm×6mm) with excellent solderability
    - Operating temperature range: -40? to 125?
    - AEC-Q100 qualified
  • Micro step drive, supporting up to 1/32 steps.
    - Less motor noise, smoother and more precise control
    - Uses only a simple clock input interface, with no need for an advanced functional MCU or dedicated software.
    - Constant-current PWM control: Mixed decay mode stabilizes current waveforms.
  • Stall detection function
    - A stall detection signal is output from SD pin after detecting a stall.
    - The detection signal can be received by a microcontroller and fed back to the system.


- Mirror adjustment for the projection position of heads-up displays
- Expansion valves in refrigerant circuits for automotive air conditioners and battery management systems
