![]() ![]() ![]() They do handle a peak of 3A but that's just for a short amount of time, like 20 milliseconds. Just make sure they're good for 1.2 Amp or less of current, since that's the limit of this chip. That means you can drive 2-4 solenoids (only two can be active at a time, on opposite bridges), two DC motors bi-directionally, or one stepper motor. Each breakout chip contains two full H-bridges (four half H-bridges). The TB6612 has be soldered 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. We really like these dual H-bridges, so if you want to control motors without a shield or HAT these are easy to include on any solderless breadboard or perma-proto. Spin two DC motors, step one bi-polar or uni-polar stepper, or fire off two solenoids with 1.2A per channel using the TB6612. ![]()
