H-Bridge Driver Click Board™

Product Code: MIKROE-4696

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.
