TC648BEPA is an integrated motor driver and controller from STMicroelectronics. It is a stand-alone unit with the flexibility to be implemented in a variety of applications including home appliances, consumer electronics, small appliances, and audio-visual equipment. The TC648BEPA is a cost-effective motor-driven option with its versatile array of features and functions.

The TC648BEPA contains a three-phase brushless motor controller, a pulse-width modulation controller, and a variable speed regulator. This setup makes the TC648BEPA suitable for one of three different motor control modes: non-revolved step or sinusoidal commutation, open-loop speed control, and sinusoidal motors. The pulse-width modulation controller reduces vibrations, simplifies maintenance, and ensures quiet operation. It can be used in applications such as cooking ovens and washing machines.

The TC648BEPA is designed for inverting amplifier driving, which is characterized by low power consumption and high control accuracy. Its low-noise power-efficiency output stage reduces consumption by more than 50% compared with other directional motors and controllers. The device also reduces junction temperatures by up to 10°C compared with other alternatives and is designed to withstand harsh industrial conditions.

The TC648BEPA also offer integrated protection features, such as over-temperature, over-voltage, under-voltage, and load protection. It also includes a range of features such as over-current protection, under-power protection, and current-limiting functions. By utilizing these features, motor current and system temperature are kept within safe ranges, protecting the motor and its drive system from both thermal and electrical damage.

The motor speed and the angle of the components of the motor can be controlled by programming the system registers. The setting of the motor speed, torque and current, as well as the selection of the commutation sequence, can be configured through the open-loop control or dynamically adjusted through the closed-loop feedback control.

The TC648BEPA also contains a number of diagnostic and maintenance capabilities, which allow for improved system performance and reduced maintenance costs. These capabilities include automatic diagnostics of the motor’s power supply, bus voltage, and operating temperature. In addition, the TC648BEPA has a wide range of on-chip self-diagnostic functions, making it ideal for embedded applications, such as in process automation, automotive, and industrial applications.

Overall, the TC648BEPA is a high-performance and cost-effective motor controller and driver. It is suited to a range of systems and can be used in applications such as consumer electronics, major appliances, and audio-visual equipment. It provides integrated protection features and is capable of operating in both open- and closed-loop modes. By using the TC648BEPA as a motor controller and driver, equipment designers can leverage its reduced cost, high performance, and increased safety features.
