Toshiba TB67S531FTG 40V/2.0A Bipolar Stepper Motor Driver IC
Toshiba's TB67S531FTG improves noise immunity to prevent step-out, enabling stable and reliable control in demanding industrial environments
Toshiba's TB67S531FTG is a 40V, 2A two-phase bipolar stepper motor driver IC for industrial, commercial, and office equipment.
The device features a phase input interface for motor current control, a typical RDS(ON) of 0.8Ω, and integrated current control and charge pump circuits.
It supports full-, half-, and quarter-step operation and includes thermal shutdown, over-current detection, and under-voltage lockout functions.
Key features
- Phase input interface: Prevents missing steps in noisy industrial environments
- 40V / 2.0A output: Robust performance to drive a wide range of industrial stepper motors
