특징

  • HOW DOES IT WORK?

    DC Motor 29 Click is based on the DRV8245P, an automotive H-Bridge driver with integrated current sense and diagnostic from Texas Instruments. The driver operates from 4.5V up to 35V and supports a wide range of output load currents for various motors and loads. It integrates an N-channel H-bridge, charge pump regulator, high-side current sensing with regulation, current proportional output, and protection circuitry. The H-bridge output power stage can be operated in different control modes, which allows you to drive a single bidirectional brushed DC motor or two unidirectional brushed DC motors over screw terminals. The driver offers voltage monitoring, load diagnostics, and protection features against overcurrent and overtemperature.

    DC Motor 29 Click uses a standard 4-wire SPI serial interface to communicate with the host MCU. The TXS0104, a 4-bit bidirectional voltage-level translator from Texas Instruments, does the logic-level translation. The driver load current analog feedback is available over the IP pin. The controller input 1 for bridge operation is available over the IN1 pin.

    The PCA9538, an 8-bit I/O port from NXP, provides additional functionalities from the motor driver to the host MCU and can be reset over the RST pin. It provides an input of the controller input 2 for bridge operation. These two controller inputs allow you to use different control schemes. The mode scheme can be changed anytime over the software. The I/O port also allows you to disable the motor driver. The fault conditions are also monitored over this IC. If a fault condition occurs, the host MCU will be asserted over the FLT pin. The I2C address of the I/O port can be selected over the ADDR SEL jumpers.

    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.
