TB67H400AHG

The TB67H400AHG is a device used to control motors and other motors, meaning it can be found under PMIC - Motor Drivers, Controllers. It is a high performance, highly efficient motor driver, providing four switch outputs which can be configured as either full-H, or full-bridge, and four PWM outputs controlled by analog input signal.

Application Field

The TB67H400AHG is predominantly used in robotics applications and is seen as the primary drive for robotic arms, legged robots and other automotive applications. It is incredibly reliable and provides up to 18V peak voltage for the motors it is controlling, which is more than enough for most robotics applications and other motor control applications.

It is designed for use in harsh environments and can be adapted for use in a wide range of conditions; from humid conditions to high temperatures, snow and rain. Its waterproof capabilities are what draw most people to it, as it can guarantee safe operation in the most extreme conditions.

The TB67H400AHG is also used in automotive services, such as cars and trucks, allowing it to control varying motor speeds and the operation of headlights, horns and seat-belt warning functions. It is also used in aiding the operation of advanced driver assistance systems and security systems, granting it a wide range of viable applications in the automotive field.

Working Principle

The TB67H400AHG uses a four-input full H-bridge and four PWM matching output to achieve high switching frequency and high efficiency speed and torque control. Each bridge consists of two power outputs, an analog input, a ground and an enable/disable input. The analog input allows the device to be set to a certain level to provide the appropriate torque or speed for the application. The enable/disable control input allows the user to enable or disable the device at any time, and provide a level of control.

The full H-Bridge allows the device to control both direction and speed of a DC motor, and the TB67H400AHG is configured to allow different levels of speed and torque to be achieved. Additionally, it has a dead-zone feature, which allows a small gap in the switching of the H-Bridge, allowing for increased accuracy and smoothness in the operation of the device.

The four PWM outputs are part of the device\'s main operations, allowing it to offer speeds levels of up to 18V, with a relatively small power draw. Having separate PWM outputs also allows for increased accuracy, as different speeds can be set across different outputs to give better control over the device.

Conclusion

The TB67H400AHG is a versatile and robust motor driver, allowing robotics and automotive applications to be operated with high efficiency and reliability. The four-input full H-Bridge and PWM outputs give it the necessary features to be used in harsh environments, whilst still providing excellent accuracy. Whether it is controlling a robotic arm, headlights or security systems, the TB67H400AHG will provide the necessary control and reliability to get the job done.
