특징

  • HOW DOES IT WORK?

    H-Bridge 14 Click is based on the DRV8873, an automotive H-Bridge motor driver from Texas Instruments. It uses two logic inputs to control the H-Bridge driver, which consists of four N-channel MOSFETs. Those MOSFETs drive motors bi-directionally with up to 10A peak current. The motor has a configurable motor interface, a PH/EN or PWM, and an independent half-bridge control. The selection can be made over the software and the host MCU. The motor driver integrates current sensing and features proportional current output. It also features protections such as VM under-voltage lockout, charge pump undervoltage, overcurrent protection, open load detection, thermal shutdown, fault conditions, and more. The power supply for the motor can be selected between the external and the 5V from the mikroBUS™ power rail.

    H-Bridge 14 Click uses a standard 4-wire SPI serial interface to communicate with the host MCU. Two control inputs are labeled IN1 and IN2. The onboard PCA9538 8-bit I/O port from NXP controls the sleep and bridge disable inputs. It also monitors the fault indication pin of the motor driver and interrupts the host MCU over the INT pin. The I2C address of the PCA9538 can be set over the ADDR SEL jumper. This I/O port can be reset over the RST pin.

    This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this 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.
