Sensorless BLDC control at ultra-high supply voltages (up to 18 V) is often required in many applications such as drone ESCs and DC fans. This reference design is based on NXP's highly integrated 8-bit S08 microcontroller MC9S08SU8/16. With its compact design, the BLDC control board delivers outstanding performance at a very low cost.
