New Brushless DC motor control SoC Flash MCU, the BD66FM8452F. This new device integrates an MCU, an LDO, a three-phase 32V driver, a VDC bus voltage detection function and a high-voltage FG circuit. This all-in-one solution greatly simplifies the usual peripheral circuit and allows for much smaller PCBA areas, making the device suitable for use in low profile products which have small PCBA requirements. To increase system security and stability, the device provides many protection functions which include Over Current Protection, VCC Under Voltage Lock-Out, Output Short-circuit Protection and Over Temperature Protection. This device is suitable for use in three-phase BLDC motor products with voltages below 24V and power ratings below 18W, such as sweeping robot driving motors, low-wattage fans, pumps, etc.
