Single microcontroller 600W BLDC motor control circuit design for low-power Bluetooth

This reference design provides the Bluetooth® 5.0 SimpleLinkTM option, which has better industrial noise suppression capabilities, wider ranges, and lower power consumption for a variety of industrial applications, such as 5 lithium-ion batteries. Power tool. This power grade reference design uses a single low-power Bluetooth (BLE) MCU for wireless connection and three-phase brushless DC (BLDC) motor trapezoidal control, which is designed on a single board, thereby reducing BOM and total costs. This design can also exhibit the RF performance of RF performance even when the power stage drive motor is driven, thereby reflecting the robustness of RF performance. This design also shows small-sized power levels with overcurrent and short-circuit protection (by MOSFET VDS induction). Characteristic Single MCU integrates motor control functions and BLE connections 600W BLDC motor driver for operating voltage is 6V to 21.6V supports 27Arms continuous winding current, no heat sink, 33mm x 45mm small dimensions Bluetooth 5.0 SIMPLINKTM solution with 61μA / MHz Cortex M3 MCU and additional sensor controller based on the proprietary kernel The best RX sensitivity: even is -96dBM even when the motor is running (approximately) BLE ultra low power operation, the average current is less than 10μA, the connection interval is 1s, the sleep current is 1μA
