DC MOTOR 3 click 1 DC MOTOR 3 click DC MOTOR 3 click DC MOTOR 3 click IC/Module Interface Power supply Website TB6549FG [1] PWM, IN1, IN2, SLP 3.3V www.mikroe.com/click/dc-motor-3 [2] 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 4.5 A with 30V, making it suitable for high-power motors. Features and usage notes 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. Schematic also available in PDF [3] For safety, the TB6549FG IC incorporates overcurrent protection 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. Summary of TB6549FG specifications: • • • • Power supply voltage: 30 V (max) Output current: 3.5 A (max) (FG,PG type) Low ON-resistance: 1.0 Ω (up + low/typ.)
