Das H-Bridge 10 Click Board™ ist eine kompakte Zusatzplatine mit H-Brückenausgängen, mit denen Sie einen Gleichstrommotor vorwärts oder rückwärts steuern können. Diese Platine verfügt über den MP6523, einen dreifachen Halbbrücken-DMOS-Ausgangstreiber mit integrierten Leistungs-MOSFETs, der bis zu drei verschiedene Lasten von monolithischen Stromversorgungssystemen (MPS) antreiben kann. Der MP6523 ist für einen Betriebsspannungsbereich von 7 V bis 28 V ausgelegt. Er ist SPI-konfigurierbar und verfügt über verschiedene Diagnosefunktionen. Zu den vollständigen Schutzfunktionen gehören Kurzschlussschutz (SCP), Unterspannungsschutz (UVP) und thermische Abschaltung sowie eine integrierte Stromversorgungs-Existenzprüfungsschaltung. Dieses Click Board™ eignet sich als Mehrfachbürsten-Gleichstrommotortreiber zum Antreiben verschiedener Lasten in Automobil- und Industrieanwendungen und mehr.
Das H-Bridge 10 Click Board™ wird von einer mikroSDK-kompatiblen Bibliothek unterstützt, die Funktionen enthält, die die Softwareentwicklung vereinfachen. Dieses Click Board™ wird als vollständig getestetes Produkt geliefert und ist bereit für den Einsatz auf einem System, das mit der mikroBUS™-Buchse ausgestattet ist.
How Does The H-Bridge 10 Click Board™ Work?
The H-Bridge 10 Click Board™ as its foundation uses the MP6523, a triple, half-bridge motor driver from Monolithic Power Systems (MPS). The MP6523 contains three MOSFET half-bridge outputs that can drive up to three different loads with separate controls for high-side or low-side MOSFETs from a standard serial data interface. It has a low quiescent current in standby mode, making it suitable for many applications. The input voltage ranges from 7V to 28V, with up to 0.9A output current capability per channel. Complete protection features include short-circuit protection, under-voltage protection, and thermal shutdown.
The H-Bridge 10 Click Board™ communicates with MCU through a standard SPI interface and operates at clock rates up to 3MHz, providing data in digital format of 16-bits. It also can be enabled or disabled through the EN pin routed to the PWM pin of the mikroBUS™ socket; hence, offering a switch operation to turn ON/OFF power delivery to the MP6523. It also provides a fault status indication signal, labelled as FLT and routed to the INT pin of the mikroBUS™ socket, alongside its red LED indicator marked as FLT to indicate different fault conditions such as current limit and thermal shutdown.
A unique addition that this board has is checking the existence of an external power supply. By adding resistors R4 and R5, the user can monitor and check the presence of an external power supply on the VS terminal via the voltage divider routed to the AN pin of the mikroBUS™ socket.
The H-Bridge 10 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 the communication lines properly. However, the Click board™ comes equipped with a library that contains easy-to-use functions and an example code that can be used, as a reference, for further development.

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. UART terminal is available in all MikroElektronika compilers.
MIKROSDK
The H-Bridge 10 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.
