Das H-Bridge Driver Click Board™ ist eine kompakte Zusatzplatine, die einen H-Brücken-Gate-Treiber enthält, auch Vollbrücken-Vortreiber genannt. Diese Platine verfügt über den MC33883, einen H-Brücken-Gate-Treiber mit integrierter Ladungspumpe und unabhängigen High- und Low-Side-Gate-Treiberkanälen von NXP Semiconductors. Die Gate-Treiberkanäle werden unabhängig voneinander durch vier separate Eingangspins gesteuert, sodass das Gerät optional als zwei unabhängige High-Side-Gate-Treiber und zwei unabhängige Low-Side-Gate-Treiber konfiguriert werden kann. Gate-Treiberausgänge können Spitzenstromimpulse von bis zu 1,0 A liefern und aufnehmen, wodurch große Gate-Lade-MOSFETs angetrieben und/oder hohe Pulsweitenmodulationsfrequenzen (PWM) genutzt werden können.
Das H-Bridge Driver Click Board™ eignet sich für Automotoranwendungen (elektrische Pumpen), Energiespeichersysteme (ESS), unterbrechungsfreie Stromversorgung (USV) und mehr.
How Does The H-Bridge Driver Click Board™ Work?
The H-Bridge Driver Click Board™ as its foundation uses the MC33883, an H-bridge gate driver (or full-bridge pre-driver) with integrated charge pump and independent high and low-side driver channels from NXP Semiconductors. Gate driver outputs can source and sink up to 1.0A peak current pulses, permitting large gate-charge MOSFETs to be driven and/or high pulse-width modulation (PWM) frequencies to be utilized. It also supports a Sleep mode of operation with its low supply current, typical of 10μA.
The VIN1 and VIN2 terminals are the power supply inputs to the device. VIN1 is used for the output high-side drivers and the charge pump, while VIN2 is used for the linear regulation. They can be connected together or with different voltage values with VIN1 up to 45V and VIN2 up to 28V. These pins also have under-voltage (UV) and overvoltage (OV) shutdown features. If one of the supply voltage drops below the under-voltage threshold or rises above the overvoltage threshold, the gate outputs are switched low to switch off the external MOSFETs. When the supply returns to a level above the UV threshold or below the OV threshold, the device resumes normal operation according to the established condition of the input pins.
The gate driver channels are independently controlled by four separate pins, routed to the RST, AN, PWM, and INT pins of the mikroBUS™ socket. Those pins allow the device to be optionally configured as two independent high side gate drivers and two independent low side gate drivers. In addition, it also has a pin used to place the device in Sleep mode. When the GEN pin, routed to the CS pin of the mikroBUS™ socket, is in a logic low state, the device is in Sleep mode; otherwise, it is fully operational.
The H-Bridge Driver Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it allows both 3.3V and 5V capable MCUs to use the GPIO 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 Click Board™ on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Library Description
The library covers all the necessary functions to control the H-Bridge Driver Click Board™. Users can use functions that control four separate input pins.
Key Functions
void hbridgedriver_glo_enable ( uint8_t state );- Function is used to turn the device on or off.void hbridgedriver_in_ls_2 ( uint8_t state );- Function is used to set the state of the 'IL2' pin.void hbridgedriver_in_ls_1 ( uint8_t state );- Function is used to set the state of the 'IL1' pin.
Example Description
The application is composed of three sections :
- System Initialization - Initializes GPIO and LOG structures, and sets AN, RST, CS, PWM and INT pins as output and start to write log.
- Application Initialization - Initializes GPIO driver and turns the device on.
- Application Task - Demonstrates use of the H-Bridge Driver Click board™ by turning connected MOSFETs gates high or low in order to drive the motor forward, in reverse, brake or coast.
void application_task ( ) { mikrobus_logWrite( "The motor turns forward!", _LOG_LINE ); hbridgedriver_forward( ); Delay_ms( 1000 ); mikrobus_logWrite( "The motor brakes!", _LOG_LINE ); hbridgedriver_braking( ); Delay_ms( 1000 ); mikrobus_logWrite( "The motor turns in reverse", _LOG_LINE ); hbridgedriver_reverse( ); Delay_ms( 1000 ); mikrobus_logWrite( "The motor coasting", _LOG_LINE ); hbridgedriver_coasting( ); Delay_ms( 1000 ); }
The full application code, and ready to use projects can be found on our LibStock page.

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 H-Bridge Driver 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.
