TC642EUA

Motor Drivers, Controllers, and TC642EUA are all active components integrated into the larger power management integrated circuit (PMIC) product family. As a powerful and versatile member of the PMIC family, TC642EUA is a single-chip solution with unique Pulse-code modulation (PCM) Current Control Mode applications. It is designed to provide integrated solutions to current control, voltage regulation, and other design requirements in motor control and power electronic industries.

Before discussing the application field and working principle of TC642EUA, some general knowledge about PMIC should be introduced. As an integrated device, PMIC collects and controls many active components such as capacitors, power switches, transistors and more, which are essential components for power management. By combining these components, PMIC can save designers from building separate circuits and complete these power control functions much faster. The main functions of PMIC can be divided into three categories: power management, power regulation, and current control.

As a powerful and versatile PMIC device, TC642EUA can handle a wide array of applications, including motor control, power electronics, and power management. By integrating current control, voltage regulation, and other features, TC642EUA can accelerate the development process and help designers save time and cost.

Motor control can be divided into two categories. First, there’s open loop motor control, which uses control system with feedback signal. This type of motor control requires complex control algorithm, is costly and difficult to implement, and is able to provide low power and low accuracy results. The second one is closed loop motor control, which uses pulse-width modulation (PWM) to control the motor power via electronic commands. This type of motor control provides better results than open loop but can be difficult to implement due to its complexity and cost.

TC642EUA is designed to simplify the development process for closed loop motor control. It integrates advanced PCM Current Control Mode to provide multiple solutions for various motors, including Permanent Magnet Synchronous Motors (PMSM), Stepping Motors (SM) and Brushless DC Motors (BLDC). By using PCM Current Control Mode, designers can easily achieve higher accuracy and better performance in their motor designs.

TC642EUA has two main working mechanisms: the Current Regulation and Voltage Regulation. By using the Current Regulation, the device can detect the continuous current concentration of a motor and adjust the operating mode accordingly. This helps to maintain the desired current profile for efficient motor performance. On the other hand, the Voltage Regulation allows the device to dynamically adjust the voltage to maintain the desired output voltage according to the motor speed and load.

In addition, TC642EUA also features a range of features to help protect and prolong the motor lifetime, such as over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), and OTD temperature protection (OTP). Moreover, it also supports low-power logic design and external standby function, helping to reduce unnecessary power consumption and increase system efficiency.

To sum up, TC642EUA is a single-chip solution that can help accelerate the development process for various motor control and power electronic projects. With its PCM Current Control Mode and various other features, it provides a highly reliable, efficient, and versatile solution for a wide range of applications.
