TB6612FNGDual brushed-DC motor driver
Drive, reverse, brake or coast two small motors.
TB6612FNG contains two MOS H-bridges for brushed DC motors. Each channel has two direction inputs and a PWM input; a shared STBY input disables both channels. The example uses a 5 V motor rail, 3.3 V logic and two small motors. All duplicated motor-output contacts are joined, all three VM pins are powered and every ground contact is connected. Unlike coast, short brake connects both motor terminals LOW. PWM alternates drive and brake when direction inputs are opposite. Check motor stall current and PCB heating before choosing a duty cycle.
