S08 Sensorless BLDC Control

SENSORLESS-BLDC-ESC

Roll over image to zoom in

Sensorless BLDC control under ultra-high supply voltage (up to 18 V) is frequently required in many applications such as drone ESC and DC fan. This reference design is based on NXP's highly-integrated 8-bit S08 microcontroller MC9S08SU8/16. With its compact design, the BLDC control board can achieve great performance at a very low cost.
