Toshiba TB67S539FTG bipolar stepper motor driver IC
Toshiba TB67S539FTG bipolar stepper motor driver IC is a two-phase bipolar stepper motor driver that uses a PWM chopper. TB67S539FTG adopts BiCD process and has an absolute maximum rated current of 40V/2.0A. The TB67S539FTG stepper motor can be operated by a single VM power supply through a built-in voltage regulator. The device adopts QFN32 5mm x 5mm packaging and reduces external components.
