The iU6398 is a highly integrated, code-free FOC motor control product designed to simplify BLDC motor control design. It integrates a motor controller, a three-phase gate driver (supporting up to 160V N/N MOSFETs), a high-voltage Buck controller, and a 5V LDO into a compact QFN32 4x4 package. It suitable for 12V to 80V systems. It supports both sensor-less and sensor-based BLDC motor control configurations. The device provides a cost-effective and highly reliable sensor-less control solution with a minimal footprint, while also enabling efficient handling of sensor inputs for enhanced startup performance and accurate position feedback. With its high integration and robust performance, the iU6398 is perfect for precision control applications requiring high efficiency and stability, such as AI servers, high-performance computing (HPC), and industrial equipment.
