KA44370A-VB(T)
A gate driver IC for driving single-phase motors
Supplier:
Nuvoton
Certification:
KA44370A is a gate driver IC for driving single-phase motors. The output stage, which can directly drive an external power MOSFET at 48V, is assembled in a small 4mm x 4mm QFN package, making it possible to mount the IC on a small motor despite the 48V requirement. The motor current waveform can be selected from a sinusoidal or a trapezoidal wave, which is generated by our unique Auto Phase Control technology, achieving low power consumption, low vibration and high airflow with high-speed rotation. A2PRaS (Advanced Auto Phase & Rapid Softswitch) function is also installed which allows the setting of advanced phase in order to achieve even higher speed rotation. It provides optimal motor drive control for a variety of applications. Stable and reliable motor start-up is possible even in the case of mutual interference when multiple fan motors are used, or when reverse rotation takes place due to external airflow.
