STMicroelectronics AEK-MOT-3P9908M Evaluation Board is based on the SPC560P Pictus 32-bit MCU and the L9908 gate driver enabling the control of 6 N-channel FETs for brushless motors in automotive applications. The AEK-MOT-3P9908M Evaluation Board facilitates independent encoder inputs and Hall sensors to detect and control motor speed.
The STM AEK-MOT-3P9908M features the L9908 3-phase motor gate driver unit that 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. Firmware is preloaded and can be externally driven via the CAN bus.
