TC646BEUA713 application field and working principleTC646BEUA713 is one of the Power Management Integrated Circuits (PMICs). It is designed to control and drive motors in various applications including consumer electronics, industrial, automotive and other motor control applications, where it helps to simplify power supply design and reduce the amount of components and cost. It has been widely used in various motor drivers, controllers and automotive systems by many manufacturers all over the world.TC646BEUA713 is a high-performance, low-cost device for controlling a wide range of motors and offers the high power efficiency for the applications it serves. It can control buzzing, brushless DC motors (BLDC) and stepper motors, as well as other applications with incorporated Hall effect sensors and electronic commutation support. It also includes a current protection mechanism.The main feature of TC646BEUA713 is its ability to include internal current sensing, which helps it to overcome the current limitation of externally applied sensors. This feature helps to provide a high accuracy and efficient power control to the motion system under all operating conditions. It also eliminates the need for external current sensing components.In addition to the internal current sensing, TC646BEUA713 also provides low voltage and high voltage protection. This ensures the safety of the system under extreme and non-standard voltage. Climatized functions are included to ensure thermal stability in operations where the motor is running at high speeds and/or high temperatures. These features, combined with a power efficient design, ensure that your motor and motor control system is more reliable and efficient.The high-performance TC646BEUA713 motor driver offers a simple, low-cost way of providing BLDC motor control. It has incorporated a digital Hall effect sensor circuit, an external digital input for commutation of the motor shaft rotation and a pulsed, voltage control analog output to control the current in the motor. An on-board comparator with adjustable hysteresis helps to maintain smooth transition from one commutation point to the next. The device also includes a duty cycle selector that can be used to select the maximum amount of current that flows through the motor during each phase of the commutation sequence.In short, TC646BEUA713 has been designed to provide power management for motors and motor control systems, with the focus on providing efficient and reliable operation. Its current sensing and thermal management features help to ensure accurate control and reliable system performance, even under harsh conditions. The digital Hall effect sensing, commutation support and the duty cycle selector help to simplify the motor control design. By using TC646BEUA713, motor and motor control systems can be easily tuned to get the highest performance while still maintaining a reasonable cost and power efficiency.
