H-Bridge Driver 2 Click

NOTE: An additional MOSFET board and DC Motor do not come in the same package with this Click board™; you can find an H-Bridge MOSFET board for H-Bridge Driver Click in our shop.

How does it work?

H-Bridge Driver 2 Click 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.

H-Bridge Driver 2 Click 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 labeled 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.

This 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.

Software Support

We provide a library for the H-Bridge Driver 2 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for H-Bridge Driver 2 Click driver.

Example key functions

• hbridgedriver2_run_forward H-Bridge Driver 2 run forward function.

• hbridgedriver2_run_backward H-Bridge Driver 2 run backward function.

• hbridgedriver2_stop_with_brake H-Bridge Driver 2 stop with brake function.

Example Description

This library contains API for the H-Bridge Driver 2 Click driver. This demo application shows the use of a H-Bridge Driver 2 Click board™.

 void application_task ( void ) 
 { 
     log_printf( &logger, "t>>> Run Forwardrn" ); 
     hbridgedriver2_run_forward( &hbridgedriver2, &global_fault ); 
     display_status( ); 
     Delay_ms( 2000 ); 

     log_printf( &logger, "t>>> Stop With Brakern" ); 
     hbridgedriver2_stop_with_brake( &hbridgedriver2, &global_fault ); 
     display_status( ); 
     Delay_ms( 2000 ); 

     log_printf( &logger, "t>>> Run Backwardrn" ); 
     hbridgedriver2_run_backward( &hbridgedriver2, &global_fault ); 
     display_status( ); 
     Delay_ms( 2000 ); 

     log_printf( &logger, "t>>> Stoprn" ); 
     hbridgedriver2_stop( &hbridgedriver2, &global_fault ); 
     display_status( ); 
     Delay_ms( 2000 ); 
 }

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.HBridgeDriver2

Additional notes and informations

Depending on the development board you are using, you may need 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

This 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.
