Description: TB6612FNG - dual channel 13.5V/1A motor controller - Polol 713.
The H-bridge TB6612FNGis a high-performance motor controller in a small and SSOP24 enclosure. The Polol company has met the expectations of users and created a module containing TB6612FNG system and passive components needed for its proper operation.
The signals have been output on traditional pins (2.54 mm raster).The module can be plugged into the contact board orconnected by wires.
| For Arduino users there is a library available for easy operation of the module. |
Motor controller outputs
| Pin | Description |
|---|---|
| VCC | power supply for the logical part |
| VMOT | motor power |
| GND | mass |
| AO1 AO2 | Channel A outputs |
| BO1 BO2 | Channel B outputs |
| PWMA | Channel A PWM signal |
| PWMB | Channel B PWM signal |
| STBY | Pull up to the VCC to turn the system on, the low state (default) switches the system to a sleep state (low power consumption) |
| AIN1, AIN2 | channel A direction control |
| BIN1, BIN2 | channel B direction control |
All logical signals are internally pulled up to ground. The maximum PWM frequency is 100 kHz.

The TB6612 can be used as a controller for Polol micromotors.If the motors are subject to a standstill, it is recommended to merge the channels in order to achieve greater current efficiency. For this purpose, the following leads should be connected together:
- AO1 with BO1
- A02 with BO2
- PWMA with PWMB
- AIN1 with BIN1
- AIN2 with BIN2
Diagram
The module contains a soldered bridge with goldpin leads, with a standard 2.54 mm grid. Filtering capacitors are also placed on the board, which makes the proper connection to the microcontroller sufficient for the system to work properly. The diagram is available at this address.
Other motor controllers , including a separate TB6612, are also available.
