It comes with a whole package of features such as High-efficiency, adjustable speed control, 1.2 A output current, 2 A Output peak current, PWM & LUX techniques for operation, open collector outputs, current sensing circuitry, thermal shutdown protection and more.

Applications

The TB67S102AFTG,EL is an ideal component for applications that require controlling motors. It is used in robotic applications such as robots arms, vectored propulsion systems, and robotic legs; it is also used in large printer and scanner devices, electric vehicles and electronic actuators etc. It can also be used to build wind turbine controller, aeration control system and other small power conversions.

Working Principle

The TB67S102AFTG,EL employs PWM (Pulse Width Modulation) to control the speed of the motor. The switching frequency of the PWM signals is set using a frequency divider and a logic circuit. The speed of the motor is then set by applying an analog voltage level to an input on the driver. A higher voltage input results into a higher output frequency and vice versa. Apart from the PWM technique, this device also employs the LUX (Linear Volts per Hertz) technique to control the motor speed. This technique utilizes an applied voltage to control the motor speed based on a predefined relation.

Current Sensing

The TB67S102AFTG,EL also uses current sensing to provide feedback about the load current. This feedback is then used to regulate the output current and prevent it from exceeding the set level. The device also provides several protection circuits such as thermal shutdown and under-voltage protection. These protections help to protect the device from any undesired reaction resulting from too high temperatures or too low input voltages.

Conclusion

The TB67S102AFTG,EL is an excellent power management IC which provides a reliable, adjustable and high-efficiency motor control solution. It is suitable for a wide range of applications requiring motor speed control. This device provides current sensing, thermal shutdown and under-voltage protection which helps protect the device from any undesired reaction.
