TB6612FNG motor driver

Introduction

The TB6612FNG motor driver can control up to two DC motors at a constant current of 1.2A (3.2A peak). Two input signals (IN1 and IN2) can be used to control the motor in one of four function modes - CW, CCW, short-brake, and stop. The two motor outputs (A and B) can be separately controlled, the speed of each motor is controlled via a PWM input signal with a frequency up to 100kHz. The STBY pin should be pulled high to take the motor out of standby mode.
Logic supply voltage (VCC) can be in the range of 2.7-5.5VDC, while the motor supply (VM) is limited to a maximum voltage of 15VDC. The output current is rated up to 1.2A per channel (or up to 3.2A for a short, single pulse).

Specification

• Power supply voltage: VM=15V max, VCC=2.7-5.5V
• Output current: Iout=1.2A(average) / 3.2A (peak)
• Standby control to save power
• CW/CCW/short brake/stop motor control modes
• Built-in thermal shutdown circuit and low voltage detecting circuit
• Filtering capacitors on both supply lines

int STBY=4;
int BIN1=5;
int BIN2=6;
int PWMA=10;// enable pin 1
int PWMB=11;// enable pin 2
// D2 and D3 as a set, D5 and D6 as a set
// D10 and D11 as enable pins for DC motors
void setup()
{
  int i;
  for (i=2;i<=6;i++) // Ardunio motor driver module
  pinMode(i,OUTPUT); // set digital pins 2,3,4,5,6 as output
  pinMode(10,OUTPUT);// set digital pins 10, 11 as output
  pinMode(11,OUTPUT);
}
void loop()
{
  // 2 DC motor rotate CW for 1S, and rotate CCW for 1S
  // rotate CW
