How Does The DC Motor 23 Click Board™ Work?
The DC Motor 23 Click Board™ is based on the TB67H480FNG, a dual-channel, H-bridge, brushed DC motor driver from Toshiba Semiconductor. The TB67H480FNG has a current limit function that monitors the current flowing in the motor. When the motor current reaches the set current value, determined using onboard VREF trimmers (VREFA and VREFB), it shifts to Decay mode, selectable by positioning the SMD jumper labelled as DECAY to an appropriate position marked as 0 and 1, for a fixed OFF time and attenuates the current. The TB67H480FNG has a built-in regulator that allows the motor to be driven by a single power supply, provides a motor output voltage rating of around 40V, and has integrated protection mechanisms such as over-current, over-temperature, and under-voltage lockout for error detection.
The setting current value can be adjusted with the torque function (100%, 71%, 38%, or 0%), controlled through the PCA9538A port expander, which establishes communication with the MCU via the I2C serial interface. Lowering the torque setting can suppress the motor current when high torque is not needed. In addition to these torque setting pins, with the help of the expander, it is also possible to control some other signals, such as the control signals for selecting the operating mode of the motor driver. These pins, in combination with ENA and ENB pins, routed to default positions of CS and PWM pins of the mikroBUS™ socket, enable operational modes like CW, CCW, or short-brake.
The PCA9538A also allows choosing the least significant bit (LSB) of its I2C slave address by positioning SMD jumpers labelled as ADDR SEL to an appropriate position marked as 0 and 1, alongside its interrupt feature routed to the INT pin of the mikroBUS™ socket. Besides, all circuits can be stopped using the Sleep function, routed to default positions of the AN pin of the mikroBUS™ socket, and thus enable power saving mode, while the RST pin provides a general-purpose reset function.
The DC Motor 23 Click Board™ supports an external power supply for the TB67H480FNG, which can be connected to the input terminal labelled as VM and should be within the range of 8.2V to 44V, while the two brushed or one stepping motor coils can be connected to the terminals labelled as B+, B-, A-, and A+.
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. 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.
