How does the tb6612fng work?

Table of Contents

The TB6612FNG is an easy and affordable way to control motors. The TB6612FNG is capable of driving two motors at up to 1.2A of constant current. Inside the IC, you’ll find two standard H-bridges on a chip allowing you to not only control the direction and speed of your motors but also stop and brake.

How do I connect a tb6612fng to a breadboard?

These pairs (01 and 02) will drive each motor – the TB6612FNG will switch the polarity and control the voltage of these to determine the direction and the speed that the motor spins in. 1. Connect the power from the bottom rail 2. Connect the outputs to the breadboard, ready to accept the motor connections.

How to install a tb6612fng breakout board?

Place the TB6612FNG breakout board onto the breadboard. It needs to straddle the break down the middle of the breadboard so as to keep the two rows of pins on separate circuits.

How do you Power Your arduino/tb6612fng Motors?

My breadboard has 2 power rails – I use one (the top one in the images) to provide the Arduino/TB6612FNG power, and the other (the bottom one) to provide the Motor’s power. You need to drive the motors from a separate power source as the current the motors draw is likely to be too much for the Arduino to handle.

How many motors can the tb6612fng drive?

The TB6612FNG is capable of driving two motors at up to 1.2A of constant current. Inside the IC, you’ll find two standard H-bridges on a chip allowing you to not only control the direction and speed of your motors but also stop and brake.

How do you solder a tb6612 motor to a breakout board?

We solder on TB6612 onto a breakout board for you here, with a polarity protection FET on the motor voltage input and a pullup on the “standby” enable pin. Each breakout chip contains two full H-bridges (four half H-bridges). That means you can drive four solenoids, two DC motors bi-directionally, or one stepper motor.

What is the difference between MOSFET-based and BJT-based H-Bridges?

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).
