Bipolar stepper driver with integrated power stage
The TB6674FAG,8,EL from Toshiba is a fully integrated bipolar stepper motor driver — the control logic and the Power MOSFET output stage are on the same die, so no external driver FETs are needed for the half-bridge pair.
The operating temperature range is -30°C to 75°C ambient, which covers most indoor and sheltered industrial enclosures but does not reach the 85°C ceiling of some sibling drivers — keep the airflow or derate if the local ambient near the driver exceeds 75°C.
