Produktbeschreibung

Overview

The TB6612FNG (308k pdf) is a great dual motor driver that is perfect for interfacing two small DC motors such as our micro metal gearmotors to a microcontroller, and it can also be used to control a single bipolar stepper motor. The MOSFET-based H-bridges are much more efficient than the BJT-based H-bridges used in older drivers such as the L298N and Sanyo’s LB1836M, which allows more current to be delivered to the motors and less to be drawn from the logic supply (the LB1836 still has the TB6612 beat for really low-voltage applications). Our little breakout board gives you direct access to all of the features of the TB6612FNG and adds power supply capacitors and reverse battery protection on the motor supply (note: there is no reverse protection on the Vcc connection).

In a typical application, power connections are made on one side of the board and control connections are made on the other. All of the control inputs are internally pulled low. Each of the two motor channels has two direction control pins and a speed control pin that accepts a PWM input with a frequency of up to 100 kHz. The STBY pin must be driven high to take the driver out of standby mode.

The distance between the header rows on the PCB is 0.1" smaller than a standard 0.6" DIP package (e.g. the Baby Orangutan), but the pin spacing allows it to conveniently fit in 0.1" breadboards and perfboards.

For a more advanced motor controller based on this driver, please consider the qik 2s9v1 dual serial motor controller. For a robot controller based on this driver, please consider the Baby Orangutan, Orangutan SV-328, Orangutan SVP-1284, and 3pi robot, which connect the TB6612 to a user-programmable AVR microcontroller. For a similar motor driver that is easy to use with Arduinos, consider our DRV8835 dual motor driver shield, and for a similar motor driver with a much higher maximum operating voltage, consider our A4990 dual motor driver carrier.
