he DRV10866EVM (evaluation module) provides a cost effective, low voltage, sensorless-solution for running a 3-phase BLDC motor in 150 degree trapezoidal commutation.

The DRV10866EVM is a complete solution for evaluating the DRV10866 5-V, three-phase sensorless BLDC motor driver. It includes a TLC555 timer configured to supply a PWM to the DRV10866, a potentiometer to adjust the speed of the motor by varying the duty cycle of the PWM, a jumper on the FG pin to allow the use of an external pull up resistor, and a jumper on the FGS pin to set ½ or normal frequency output on the FG pin. Power can be provided with the included micro-USB cable for 5 V or externally provided, up to 5.5 V, through the power header. The PWN, FG, and GND signals are all brought out to surface mounted test points.
The DRV10866EVM is configured so that connections to only the motor and power supply are required.

• 2-5.5V supply voltage range
• 680mA peak output current
• Allows user to spin their motor in two easy steps: Attach power. Attach motor.
• Easy speed control with onboard poteometer and 555 timer
• PWM and FG connect pins allow for optional closed loop MCU control
• Fully protected and robust solution
