STL065L44LQ Working Principle:

STL065L44LQ adopts current control mode to realize the output of the required current. This module is composed of four parts: digital signal controller, analog signal processor, motor driving stage and power stage. The controller receives external signals from the outside world and calculates the set parameters according to the operation mode. The controller then sends the calculation results to the analog signal processor, which then performs digital-to-analog conversion and feeds the result to the motor drive stage.

The motor drive stage further amplifies the signal from the analog signal processor and adjusts the drive current according to the requirements of the external control technology. Finally, the power stage supplies power to the corresponding power devices and realizes variable speed operation. This is the working principle of STL065L44LQ.

In conclusion, STL065L44LQ has a wide range of applications, and its working principle mostly adopts current control mode to realize the output of required current. Its low cost and high efficiency make it become increasingly popular in the current market.
