Automotive 60W Brushless DC (BLDC) Motor Drive


Design files


This TIDA-00143 reference design is a BLDC motor controller and is designed to operate from a single 12V (nominal) power supply which can vary over a wide range of voltages as found in typical automotive applications.  The board is designed to drive motors in the 60W range, which require currents of 5 Amps.  The size and layout of the board is intended to facilitate evaluation of the drive electronics and firmware, with easy access to key signals on individual test points.  Connection to a wide variety of motors is possible using either the 3-contact connector or by soldering motor phase wires to plated-through holes in the board.  The 12Vdc power is fused to prevent damage to the board or to bench power supplies in case of a motor fault during testing.  Command and status of the motor can be communicated through the standard JTAG connector, or through PWM input and output signals.  Users can also re-program the microcontroller through the JTAG connector, allowing customization to a wide variety of applications.

  •  Operates from a single 12V automotive supply (7V to 40V operational range)
  •  Drives 3-phase Brushless DC (BLDC) motors up to 60W with no position sensors needed
  •  Easy to get started with MotorWare™ Software
  •  Testpoints provide easy access to key motor control signals
  •  Microcontroller programmable through JTAG connector for customization
