Toshiba TB67S128FTG Stepper Motor Controller
Toshiba TB67S128FTG Stepper Motor Controller is a two-phase bipolar clock-in and serial controlled stepping motor driver using a PWM chopper. This motor driver IC is capable of controlling one bipolar stepping motor. The TB67S128FTG stepper motor allows full, half, quarter, 1/8, 1/16, 1/32, 1/64, and 1/128 step operations. Features include built-in anti-stall architecture, built-in sense resistor less current control architecture, high voltage and current, and built-in VCC regulator for an internal circuit.
