Overview
Le Moteur à courant continu 20 Click Board™ est une carte complémentaire compacte qui contient un pilote de moteur à courant continu à balais. Cette carte comprend le TC78H651AFNG, un pilote à double pont en H pour un ou deux moteurs à courant continu à balais, qui intègre un DMOS à faible résistance à l'état passant dans les transistors de sortie de Toshiba Semiconductor. Le mode Avant/Arrêt/Arrêt peut être sélectionné en fonction de l'état de ses signaux de commande d'entrée acheminés vers les broches GPIO du socket mikroBUS™. Il dispose d'une large plage de tension de fonctionnement de 1,8 V à 7,5 V avec une capacité de courant de sortie de 2 A maximum. En outre, il dispose également d'une protection intégrée contre les conditions de sous-tension, de surintensité et de surchauffe.
Le moteur à courant continu 20 Click Board™ convient à l'entraînement de moteurs à balais à courant continu et de moteurs pas à pas pour les équipements basse tension.

How Does The DC Motor 20 Click Board™ Work?
The DC Motor 20 Click Board™ is based on the TC78H651AFNG, a dual H-bridge driver for one or two DC brushed motors from Toshiba Semiconductor. The integrated MOSFETs, which configures with an H-Bridge circuit inside the TC78H651AFNG, use DMOS elements with low-on resistance (0.22Ω typical with 5V power supply). It has a wide operating voltage range with an output current capacity of 2A maximum and control functions including motor-related functions and built-in detection circuits for overcurrent, overheat, and low/high voltage.
As mentioned in the product description, the DC Motor 20 Click Board™ communicates with MCU using several GPIO pins. Also, this Click board™ has a Standby function used to switch to Standby mode by setting all motor control pins to a low logic state. When the Standby mode is active, the TC78H651AFNG stops supplying the power to the logic circuit. The Standby current is significantly reduced because all circuits in the IC are configured with CMOS/DMOS elements, and the current consumption in this mode is 0μA typical.
To turn ON the internal MOSFETs of the TC78H651AFNG, they need to be switched by the logic level, which is input to the control input pins: IN1, IN2, IN3, and IN4 pins routed to the RST, AN, PWM, and INT pins of the mikroBUS™ socket. Thereby, the Forward/Reverse/Stop rotation direction mode can be selected according to the state of its input control signals. More information on the Motor Rotation Mode Selection can be found in the attached datasheet.
The DC Motor 20 Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use communication lines properly. However, the 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.
