Brushless click Toshiba's TB6575FNG [1] PWM,INT,AN and RST pins 5V [2] Brushless click schematic [3]

The click is able to safely drive external motors with up to 32V/2A. The board features three pairs of onboard screw terminals. VBAT is for connecting an external 7-32V power supply.

Features and usage notes

Motor position detection error

Position detection is synchronized with the PWM signal generated in the IC. When the IC is used in a high speed motor a position detection error relative to the PWM frequency may occur. The detection is performed on the falling edge of the PWM signal. An error is recognized when the pin voltage exceeds the reference voltage.

MOSFET chips

Two types of MOSFET chips on board switch the output on and off N-channel 40V and P-channel 30V . They are here for electronic motor control switching the output on and off controls the voltage levels applied to the motor and this in turn determines the speed and rotation of the motor shaft. To ensure a more secure connection there are three pairs of screw terminals - CON1 for the power supply and CON2 and CON3 for connecting to the motor. The U,V and W pins control the motor rotation direction. The Brushless click communicates with the target board MCU over the PWM pin, as well as INT, AN and RST pins.

Programming

This code snippet initializes required ports, ADC channels and PWM module. It also initializes TFT and sets motor direction. In an endless loop, if button is pressed, we increment or decrement current PWM duty by STEP, which consequently change the rotating speed of BLDC motor.
