Power management integrated circuits (PMICs) are semiconductor chips used to regulate the voltage and current used by microprocessors and other electrical systems. PMICs are widely used in embedded systems, such as automotive, robotics, industrial automation, and consumer electronics. One of the more popular PMICs is the TC642BEOA713, which is used to control motors and other power-management applications. This article will explain the application fields and working principle of the TC642BEOA713.

TC642BEOA713 Application Fields

The TC642BEOA713 is a motor driver PMIC that is suitable for a wide range of applications, such as power-management systems for automotive, robotics, and industrial automation. It is designed to control brushless DC (BLDC) fans, small motors, and pumps in machinery, such as those used in HVAC systems, robotic arms, and many other application areas.

The TC642BEOA713 integrates several features to make it suitable for motor-control applications. It includes PWM control, programmable current-sensing, and fault-flag functions. It is also capable of operating across a wide range of voltages, enabling the driver to be used in different applications.

TC642BEOA713 Working Principle

The TC642BEOA713 implements a three-phase PWM controlled motor-drive system, which is a type of motor-control methodology used in many applications. It works by generating a DC voltage from three output voltage sources, each of which is controlled by a pulse-width modulation (PWM) signal. The PWM signal can be used to vary the duty cycle of each output source, which in turn can control the speed and torque of the motor. The speed and torque are also affected by the current being applied to the motor, which can be measured using the integrated current-sensing function.

The PMIC also includes integrated fault-flag logic, which can be used to detect and report errors. The logic includes overcurrent, overtemperature, and undervoltage protection, as well as fault-signal output pins which can be used to send a signal to an external microcontroller or feedback loop.

Conclusion

The TC642BEOA713 is a powerful PMIC that is suitable for a range of motor-control applications, from automotive, robotics, and industrial automation. It is capable of operating across a wide range of voltages and implementing a three-phase PWM controlled motor-drive system. It also includes integrated current-sensing and fault-flag functions to enable safe and reliable operation of the motor.
