Das H-Bridge Driver 2 Click Board™ ist eine kompakte Zusatzplatine, die einen H-Brücken-Gate-Treiber enthält, auch Vollbrücken-Vortreiber genannt. Diese Platine verfügt über den NCV7535, einen monolithischen H-Brücken-Vortreiber für einen Gleichstrommotor mit einem erweiterten Funktionsumfang, der in Automobilsystemen von ON Semiconductor nützlich ist. Die Gate-Treiberkanäle werden unabhängig voneinander über eine 24-Bit-SPI-Schnittstelle gesteuert, sodass dieses Click Board™ optional in einem Einzel- oder Dual-H-Brückenmodus konfiguriert werden kann. Es verfügt über einen großen Betriebsspannungsbereich von 6 V bis 18 V mit integrierten Schutzfunktionen gegen Kurzschluss, Unter-/Überspannung, Überstrom und Übertemperatur. Dieses Click Board™ eignet sich zum Ansteuern externer MOSFETs und ermöglicht so die Steuerung eines Gleichstrommotors.
Das H-Bridge Driver 2 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 Driver 2 Click Board™ Work?
The H-Bridge Driver 2 Click Board™ as its foundation uses the NCV7535, H-bridge gate driver (or full-bridge pre-driver) with independent high and low-side driver channels from ON Semiconductor. This monolithic H−bridge pre-driver has an enhanced feature set helpful in various applications for a DC motor drive. It allows bi-directional or uni-directional motor operations, with integrated MOSFET and load protection.
The onboard VIN terminal is the device's power supply input, allowing a wide operating voltage range from 6V to 18V. The NCV7535 also comes with built-in protection features against short-circuit and overtemperature conditions, under-voltage (UV), overvoltage (OV), and overcurrent events. When the supply returns to a level above the UV threshold or below the OV threshold, the device resumes regular operation according to the established condition of the input pins.
The H-Bridge Driver 2 Click Board™ communicates with MCU through a standard SPI interface supporting the common SPI mode, SPI Mode 0, providing data in digital format of 24-bits. It also uses the Enable pin labelled as EN and routed to the RST pin of the mikroBUS™ socket to optimize power consumption, used for its power ON/OFF purposes. Besides, by using the PWM signal from the mikroBUS™ socket, combined with the SPI interface and its control register, the user can also use active or passive free-wheeling bridge configurations.
The H-Bridge Driver 2 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 containing easy-to-use functions and an example code that can be used, as a reference, for further development.
