Brushless 30 Click is based on the TB9083FTG, a gate-driver IC from Toshiba Semiconductor, specifically made for automotive environments and qualified under AEC-Q100 and AEC-Q006 standards. This Click board™ leverages the TB9083FTG's capabilities, featuring a three-phase BLDC pre-driver that controls brushless motors through six onboard external MOSFETs (TPH1R104PB). Additionally, it integrates a safety relay pre-driver, ensuring an added layer of protection. The TB9083FTG also incorporates a built-in charge pump, adjustable current sense amplifiers for each motor phase oscillator circuits, and an SPI communication interface, enabling easy configuration and communication with the host MCU. To ensure reliable performance, the TB9083FTG also offers multiple error detection features, including undervoltage, overvoltage, overtemperature, and external MOSFET protection, making Brushless 30 Click a reliable choice for demanding automotive motor control applications such as electric power steering (EPS), powered brakes, and pumps.
This Click board™ is designed to support a wide range of external power supplies, accepting input voltages from 4.5V to 28V through terminals on the board's front side. It can deliver a peak output current of up to 10A, providing robust power for driving BLDC motors connected to the terminals on the bottom side. The board includes dedicated pins via the unpopulated J1 connector for the connection of the 6 PWM signals, provided by the driving device, required to drive the BLDC motor connected to the terminals of the Brushless 30 Click board™.
As previously mentioned, Brushless 30 Click communicates with the host MCU through a 4-wire SPI interface, supporting a maximum clock frequency of 2MHz, ensuring fast and reliable data transfer. The SPI interface allows for the modification of settings, such as trigger thresholds and response actions. In addition to the interface pins, the board also uses two other pins on the mikroBUS™ socket. The ALR pin is used to turn ON or OFF the motor drive and the safety pre-driver circuit. i.e. in case an abnormality situation is detected. This pin is connected to a red ALR LED indicator that provides visual alerts for such conditions. Similarly, the DAG pin functions as a diagnostic output of the TB9083FTG, offering information on whether the an error condition has been detected.. This pin is linked to an orange DAG LED indicator, which visually signals the diagnostic status.
Besides the J1 header, this board includes several other unpopulated headers offering additional functionality. The AxO (J3) header is connected to the current detector circuit, which features three motor current detector amplifiers. These outputs can amplify the differential voltage caused by the current passing through the shunt resistor connected to the motor drive, providing precise current measurements. The SRxO (J4) header is linked to the safety relay pre driver, which controls the power or motor relay connected to this unpopulated header. The safety relay pre-driver circuit is managed through the CP_RLY_CTRL SPI register and includes a built-in 500Ω resistor and a backflow prevention diode to protect against reverse connections.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
