Le DC Motor 6 Click Board™ est un pilote de moteur à courant continu à balais de type hacheur PWM, étiqueté TB67H451FNG. Ce circuit intégré comprend un canal de bloc de sortie moteur, utilisant une large gamme de tensions d'alimentation tout en fournissant un courant raisonnablement élevé aux moteurs à courant continu connectés. Les MOSFET à faible résistance à l'état passant et un contrôle PWM aident le TB67H451FNG à produire moins de chaleur, ce qui permet un entraînement efficace du moteur. De plus, le TB67H451FNG dispose de deux entrées, IN1 et IN2, qui permettent de sélectionner les quatre modes de fonctionnement : avant (sens horaire), arrière (sens antihoraire), pause courte et modes d'arrêt.
Le DC Motor 6 Click est pris en charge par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette Click Board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé de la prise mikroBUS™.
How Does The DC Motor 6 Click Board™ Work?
The main component of the DC Motor 6 Click Board™ is the TB67H451FNG, a PWM chopper-type brushed DC motor driver, produced by Toshiba. This IC uses a proprietary BiCD manufacturing process, allowing this IC to be powered by a wide range of supply voltages, from 4.5 up to 44V. Due to a very low ON resistance of the MOSFETs, it can theoretically deliver up to 3A of current to the connected load. However, many external parameters affect both the maximum voltage and the current specifications, especially when the connected load is of a complex nature, such as the DC motor. In using TB67H451FNG, the voltage should be applied to the pins of VM and VREF. The absolute maximum rating of VM supply voltage is 50V (no active). The usage range is 4.5 to 44V. The absolute maximum rating of VREF supply voltage is 5V. The usage range is 0 to 4V.
There are no special procedures of inputting a power supply and shutdown because the TB67H451FNG incorporates the under voltage lockout (UVLO). However, under the unstable state of inputting the power supply (VM) and shutdown (transient area), setting the motor operation to OFF state is recommended. After the power supply is in the stable state, the motor should be operated by switching the input signal.The absolute maximum rating of motor output current is 3.5A. Its operating range is 3A or less. The maximum current of the actual usage is limited depending on the usage conditions (the ambient temperature, the wiring pattern of the board, the radiation path, and the exciting design). Configure the most appropriate current value after calculating the heat and evaluating the board under the operating environment.
This IC controls a motor operation by PWM constant current control. The peak current value (setting current value) can be determined by settings of the current-sensing resistor (R2) and the reference voltage (Vref). When both IN1 and IN2 pins are set to L for 1 ms (typ.) or more, the operation mode enters into the standby mode. When IN1 or IN2 is set to H, the mode returns from the standby mode, and enters to the operation mode.
The tBLK is intended to avoid inrush current detection. The TB67H451FNG not only can be controlled by constant current PWM, but also by direct PWM; with IN control signals.
When the supply voltage to VM pin is 3.8V or less, the internal circuit is triggered; the internal reset circuit then turns off the output transistors. Once the UVLO is triggered, it can be cleared by reasserting the VM supply voltage to 4.0V or more (typ.)

Additional Notes and Information
Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
MIKROSDK
The DC Motor 6 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
