The TB67S105FTG IC is based on a PWM control system that is compatible with the majority of DC motor types. It offers a wide range of features and flexibility which encompass a variety of motor applications, ranging from brushed DC motor applications, such as fan motor controls, to high-performance brushless DC motor control. It is also used for automotive drive control functions, such as fuel pumps, water pumps and starter motors.

The TB67S105FTG features an EL Motor Control IC chip, which is a motor control IC optimized for brushless DC motor control. The EL Motor Control IC integrates a low-on-resistance, high-speed switch with embedded PWM (pulse width modulation) control. It also has built-in protection functions such as overcurrent, overvoltage, and overheat protection and current sensor protection.

The working principle of the TB67S105FTG is based on the use of PWM technology. PWM is a type of control system used in digital control systems, as it is capable of producing a wide range of output waveforms, including waveforms with different shapes, amplitudes, and frequencies. By providing a digital signal, such as a pulse width modulated waveform, to the motor driver, a specific motor speed can be achieved. The pulse width of the PWM signal is determined by the amount of current flowing through the motor which is monitored by the current sensing circuit. The voltage of the PWM signal is determined by the amount of power being supplied to the motor which is determined by the control and current sensors.

In summary, the TB67S105FTG is a 4-phase Motor Control Driver IC that is optimized for motor applications such as fans, automotive drives, and brushless DC motor applications. It features a low-on-resistance, high-speed switching, and a low dropout voltage characteristic that ensures increased efficiency, noise reduction, and improved reliability. The EL Motor Control IC incorporates several protection functions such as overcurrent, overvoltage and overheat protection, and a built-in current sensor protection, ensuring power efficiency and reliable performance. Furthermore, its PWM control system is perfect for digital control systems, as it is capable of creating a wide array of output waveforms with different amplitudes, frequencies, and shapes.
