This reference design offers a Bluetooth® 5.0 SimpleLink™ option with better industrial noise immunity, more range, and less power for industrial applications such as power tools that operate from a 5-cell Li-ion battery. This power stage reference design uses a single Bluetooth low energy (BLE) MCU for both wireless connectivity and three-phase brushless DC (BLDC) motor trapezoidal control, designed in a single board, reducing the BOM and hence overall cost. The design demonstrates the BLE RX sensitivity of -96 dBm even when the power stage is driving motor, showing the robustness of RF performance. The design also demonstrates a small form factor power stage with overcurrent and short-circuit protection by MOSFET VDS sensing.
