Product Overview

The S08SU-EVK from NXP is a sensorless BLDC control reference design board. 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 with very low cost. The reference design can be used as an evaluation kit for S08SU MCU, a reference for creating one's own BLDC control-related design, as well as an applicable three-phase sensorless BLDC solution. Sensorless BLDC control under ultra-high supply voltage (up to 18V) is now widely needed in tones of applications such as drone ESC, DC fan etc.
  • Compact PCB design (size 80mm x 37mm)
  • Real-time in-circuit debug through S08/RS08 or HCS12 BDM interface
  • 3 x P+ N MOSFET pair
  • Single PWM duty control
  • FreeMASTER debug tool
  • 3x phase comparator for zero-crossing detection
  • Over current/voltage protection (OCP & OVP)
  • I2C, SCI, PWT interface
