48V Industrial Fan Motor Driver

Nuvoton motor driver IC incorporates A2PRaS (Auto Advanced Phase & Rapid Softswitch) technology. Advanced phase function is generally adopted for motor driving applications with high-speed rotation. However, this technique alone is not enough to achieve high efficiency. By implementing auto-advanced phase control and rapid soft switching, our IC realizes high efficiency at a wide speed range and in each operating condition.
