TB67S145FTG
Serial controlled unipolar stepping motor driver
The TB67S145 is a serial controlled PWM chopping type, 2 phase
unipolar stepping motor driver. Using the BiCD process, the TB67S
145 can be operated with VM voltage of 45V, output voltage of
84V, and output current of 3.0A at max (absolute maximum ratings).
