Toshiba TB67S128FTG 50V/5A 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 50V/5A 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 Active Gain Control (AGC), built-in sense resistor less current control architecture, high voltage and current, and built-in VCC regulator for an internal circuit.

Features:

- BiCD process integrated monolithic IC
- Capable of controlling 1 bipolar stepping motor
- High voltage and current 50V/5A
- PWM controlled constant-current drive
- Low on-resistance (high + low side=0.25Ω (typical)) MOSFET output stage
- Allows full, half, quarter, 1/8, 1/16, 1/32, 1/64, and 1/128 step operation
- Built-in anti-stall architecture (AGC: Active Gain Control)
- Built-in “sense resistor less current control architecture” (ACDS: Advanced Current Detection System)
- High-efficiency motor current control mechanism (ADMD: Advanced Dynamic Mixed Decay)
- Speed control by clock or serial interface
- Multi error detection functions:
      - Thermal Shutdown (TSD)
      - Overcurrent (ISD)
      - Power-on-Reset (POR)
      - Motor load open (OPD)
      - Error detection (TSD/ISD/OPD) signal output function
- Built-in VCC regulator for an internal circuit
- Chopping frequency of a motor can be customized by external resistance and capacitor
