Toshiba Stepper Motor Driver Bipolar 5A Output Current 64-Pin VQFN TB67S128FTG(O,EL)

The Toshiba TB67S128FTG(O,EL) is a high-performance bipolar stepper motor driver integrated circuit designed for two-phase motors. It features a built-in clock-in decoder and is fabricated using BiCD process technology, achieving robust performance and reliability in various industrial and electronic applications.

This stepper driver offers a maximum output current of 5A and supports a wide supply voltage range from 6.5V to 44V. The device incorporates PWM controlled constant-current drive to ensure precise motor current regulation and low power dissipation with its low on-resistance MOSFET output stage, combining high and low side resistance to approximately 0.25 Ω typical.

Microstepping functionality is extensive, allowing full steps down to 1/128 microstep operations for smooth and precise motor positioning. The advanced dynamic mixed decay (ADMD) mechanism maximizes efficiency by dynamically adjusting the decay mode to optimize current control. Anti-stall architecture (AGC) and advanced current detection system (ACDS) enhance operational stability and control accuracy without the need for external sense resistors.

Safety and reliability features include multi-error detection functions such as thermal shutdown (TSD), over current shutdown (ISD), power-on reset (POR), and motor load open detection (OPD). It provides dedicated error flags for these protection features, facilitating robust motor system diagnostics and maintenance.

The compact VQFN package measuring 9mm by 9mm with a 900μm height includes a thermal pad for enhanced heat dissipation, making the driver suitable for surface mount technology (SMT) applications in dense PCB layouts typical of industrial, robotic, and automation control systems.
