TB67S128FTG is a two-phase bipolar stepper motor driver that uses a PWM chopper. Built in clock decoder. Made using BiCD technology, with an output rated value of 50 V/5.0 A (motor power supply voltage=44 V).

Toshiba TB67S128FTG stepper motor controller
The Toshiba TB67S128FTG stepper motor controller is a two-phase bipolar stepper motor driver using PWM chopping, with a built-in clock and support for serial control. This motor drive IC can control a bipolar stepper motor. The TB67S128FTG stepper motor can operate in full, half, 1/4, 1/8, 1/16, 1/32, 1/64, and 1/128 stepper modes. The features include a built-in anti stall structure, a built-in current free detection resistor circuit control structure, high voltage and high current, and a built-in VCC regulator for internal circuit use.
