نقد و بررسی اجمالی

High-current bipolar stepping motor driver درایور استپ موتور جریان بالا -سانکن ژاپن

استفاده در اکثر صنایع :

از جمله PFM  - ATM - سنایع نساجی و  ماشین آلات گلدوزی

he SX7232M is complete microstepping motor driver with built-in translator for easy operation with minimal control lines. It is operated by single power supply and no external logic supply to drive internal translator is required.
It is designed to operate bipolar stepper motors in full, half, quarter, eighth, sixteenth step modes, include 100% full torque step modes.
Internal circuit protection includes: thermal shutdown with hysteresis (TSD), undervoltage lockout (UVLO), crossover-current protection and over-current protection (OCP). OCP circuit will protect the IC from short-to-supply, short-to-ground and shorted-load.
At power-on or reset, the translator sets the DACs and the phase current polarity to the initial home state.
