TB67S105FTG
8bit Serial controlled bipolar stepping motor driver
The TB67S105FTG is a two phase bipolar stepping motor driver
using a PWM chopper, controlled by 8 bit serial.
Fabricated by the BiCD process, the TB67S105FTG is rated
at 50V/3.0A.
The internal voltage regulator allows to control the device
with a single VM power supply.
