Overview

TB6612 Specifications
• Recommended motor voltage (VMOT): 4.5 – 13.5 V
• Logic voltage (VCC): 2.7 – 5.5 V
• Output current maximum: 3 A per channel
• Output current continuous: 1 A per channel (can be paralleled to deliver 2 A continuous)
• Maximum PWM frequency: 100 kHz
• Built-in thermal shutdown circuit
• Filtering capacitors on both supply lines
• Reverse-power protection on the motor supply
Real-world power dissipation considerations
The TB6612 motor driver used on the carrier board has a peak current rating of 3 A per channel. The
peak ratings are for quick transients (e.g. when a motor is first turned on), and the continuous rating of
1 A is dependent on various conditions, such as the ambient temperature. The actual current you can
deliver will depend on how well you can keep the motor driver cool. The carrier’s printed circuit board is
designed to draw heat out of the motor driver chip, but performance can be improved by adding a heat
sink.

Note: 16 male header pins are included but not soldered onto the boards. No printed documentation is
shipped with these items; please see the TB6612FNG datasheet in the resources tab for more
information about the motor driver.
