{"product_id":"ka44370a-vbt","title":"KA44370A-VB(T)","description":"\u003cp\u003eKA44370A 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 \u0026amp; 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.\u003c\/p\u003e\u003ch5\u003eRecommended Circuit\u003c\/h5\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0664\/0749\/7934\/files\/KA44370A.png?v=1779185267\" alt=\"RECOMMENDED_CIRCUIT_KA44370A\"\u003e\u003c\/p\u003e\u003ch5\u003eSupport tool\u003c\/h5\u003e\u003ch5\u003eEvaluation Board\u003c\/h5\u003e\u003ch5\u003eKE-KA44370A  - KA44370A single-phase PWM\/VSP motor evaluaton board\u003c\/h5\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0664\/0749\/7934\/files\/KE-KA44370A.png?v=1779185270\" alt=\"KE-KA44370A\" width=\"300\" height=\"232\"\u003e\u003c\/p\u003e\u003cp\u003eThe KE-KA44370A is an evaluation board (EVB) equipped with pre-driver KA44370A, and external MOSFET drivers.
