DC MOTOR 3 Click is a mikroBUS™ add-on board with a Toshiba TB6549FG full-bridge driver for direct current motors. The IC is capable of outputting currents of up to 3.5 A with 30V, making it suitable for high-power motors.
Two pairs of screw terminals are positioned on the top of the board. One is for bringing an external power supply; the other is for connecting a motor.
TB6549FG has four operating modes: clockwise, counter-clockwise, short brake and stop. The operating mode is configured through IN1 and IN2 pins. A separately controlled standby mode is also available.
For safety, the TB6549FG IC incorporates overcurrent protetciont and a thermal shutdown circuit.
The Click communicates with the target MCU through the mikroBUS™ PWM pin, with additional functionality provided by IN1, IN2 and SLP pins (in place of default mikroBUS™ AN, RST and CS pins). Designed to use a 3.3 power supply only.
