PMIC (power management integrated circuit) is a chip that integrates multiple power management functions into a single IC. Commonly used PMICs include voltage regulators, motor drivers, controllers and other components. One of the most popular PMICs is the TB62213AFG-8-EL, which is designed to provide a wide range of motion control and protection functions. This article will discuss the application field and working principle of the TB62213AFG-8-EL motor driver controller.

Overview

The TB62213AFG-8-EL is a digital three-phase brushless DC motor driver with integrated gate driver, current shunt and overcurrent protection circuits. It has a wide range of features, including built-in gate driver, current shunt and overcurrent protection circuits, 3-phase sinusoidal or trapezoidal drive waveforms, 6-step or 8-step micro-stepping control, open- or closed-loop speed control, starting torque adjustment and speed control modes with automatic acceleration and deceleration. The device is available in a 24-pin SOIC package, making it suitable for surface-mount designs.

Application Fields

The TB62213AFG-8-EL motor driver controller can be used in a wide range of motion control applications, from robotics and automation to medical instrumentation and industrial equipment. Other applications include stepper motor control and pulsed-width modulation (PWM) motor control, as well as controlling speeds in brushless DC motors. The device\'s integrated gate driver, current shunt and overcurrent protection circuits enable it to provide a high level of performance in these applications.

Working Principle

The TB62213AFG-8-EL motor driver controller works in conjunction with a closed- or open-loop speed control system to accurately control the speed of a motor. The device has an integrated micro-stepping control function, which allows it to accurately control the speed of the motor, even during changes in direction or load. In addition, when combined with a PWM control system, the TB62213AFG-8-EL can provide precise control over the speed of the motor and a wide range of speed control modes, including automatic acceleration and deceleration.

When used in open-loop speed control applications, the TB62213AFG-8-EL relies on the internal speed control system to adjust the speed of the motor to follow the reference signal provided by the user. In closed-loop speed control applications, the device utilizes feedback signals from the motor\'s position sensors and the reference signal provided by the user to precisely adjust the speed of the motor in order to maintain the desired speed. The integrated gate driver, current shunt and overcurrent protection circuits allow the device to provide a high level of performance in these applications.

Conclusion

The TB62213AFG-8-EL is a digital three-phase brushless DC motor driver with integrated gate driver, current shunt and overcurrent protection circuits. It is designed to provide a wide range of motion control and protection functions and can be used for stepper motor control, pulsed-width modulation control, open- or closed-loop speed control and other applications. Its integrated gate driver, current shunt and overcurrent protection circuits enable it to provide a high level of performance in these applications.
