DRV11873EVM, Evaluation Board for DRV11873, 12V, 3-Phase Sensor-Less BLDC Motor Controller

DRV11873EVM, Evaluation Board is a complete solution for evaluating the DRV11873, 12V, three-phase, sensorless BLDC motor driver. It includes a TLC555 timer configured to supply a PWM to the DRV11873, 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 RD pin to indicate that the motor has entered a lock protection state. The DRV11873EVM also has a jumper on the FR pin to select forward or reverse and a jumper on the FS pin to vary for high- or low-speed motor applications. Power can be provided externally, up to 16V, through the power header. The PWM, RD, FG and GND signals are all brought out to surface mounted test points
