Motor Driver (MTD)

Nuvoton motor driver IC incorporates APC (Auto Phase Control) technology to correct the phase delay by detecting motor current automatically. With APC, there is no need for adjustment of phase. As a result, it helps to eliminate phase delay due to motor variation or deterioration and therefore realizes high efficiency, reliability, and safety motor system. Products with APC technology include KA44168A, KA44169A, KA44169AB, KA44170A, and KA44143A.
