ROHM Semiconductor BM62300MUV 3-Phase Brushless Motor Pre-Driver
ROHM Semiconductor BM62300MUV 3-Phase Brushless Motor Pre-Driver supports 24V power supply controlling the motor driver constructed in external power transistor. The BM62300MUV Pre-Driver detects the rotor position on three hall sensors. Furthermore, the ROHM BM62300MUV Pre-Driver provides a silent operation and low vibration implemented by making the output current a sin waveform.
