TB6612FNG motor driver can control up to two DC motors at a constant current of 1.2A (with a 3.2A peak). It uses two input signals (IN1 and IN2) to operate the motors in four modes: CW, CCW, short-brake, and stop. Each motor output (A and B) can be controlled separately, with speed adjustment via a PWM input signal of up to 100 kHz.
To exit standby mode, the STBY pin must be pulled high. The logic supply voltage (VCC) ranges from DC 2.7V to 5.5V, while the motor supply (VM) can go up to a maximum of 15V DC. The output current is rated at 1.2A per channel, with a short pulse capability of up to 3.2A.
