STMicroelectronics Motor Evaluation Board Brushless DC Motor for SPC560P & L9908 for BLCD Motor

The STMicroelectronics evaluation board is based on the SPC560P Pictus 32-bit MCU and the L9908 gate driver allowing the control of 6 N-channel FETs for brushless motors in automotive applications. It supports independent encoder inputs and hall sensors to detect and control motor speed. The L9908 independently controls each N-channel FET through a dedicated PWM input pin. The L9908 configuration, protection and diagnostic functions are controlled via SPI by the SPC560P microcontroller and the firmware is preloaded and can be externally driven via CAN bus. The STSWAUTODEVKIT contains a CAN bus driving example based on SPC58 Chorus. To change the motor characteristics or the control firmware on the SPC560P50L5, you need to install the SPC5-MCTK-LIB motor control plug-in in SPC5Studio.
