Design an automotive-grade sensorless BLDC motor controller circuit for an Electric Cooling Fan (ECF) application. Use an MCU from Infineon (e.g., TLE9893, TLE987x series) or NXP (e.g., S32K family), ensuring all selected components comply with AEC-Q100 or AEC-Q101 standards for automotive reliability. The system should support high-efficiency 3-phase motor control without Hall sensors, using back-EMF or sensorless FOC techniques.
Include:
  • A high-side and low-side gate driver stage suitable for 12V automotive systems
  • A 3-phase inverter power stage with AEC-Q101 qualified MOSFETs
  • Current sensing (shunt or inline) for sensorless control
  • Sigma-Delta or high-accuracy ADC integration with the MCU
  • Robust EMC filtering, ESD protection, and power conditioning (TVS diodes, LDOs, etc.)
  • CAN/LIN communication interface support
  • Protection features (overcurrent, thermal shutdown, undervoltage lockout)
Ensure the layout is optimized for automotive EMC compliance, and the BOM includes only automotive-grade (AEC-certified) passive and active components. Include DRC-verified schematics and PCB for fabrication-ready output.
