Phase Control Circuit–Load Current Feedback Applications
Description
The interated circuit, U210B1, is designed as a phasecontrol circuit for load-current feedback application in bipolar technology. To realize motor control systems, it has integrated load current detection, voltage monitoring and soft-start functions. The voltage obtained due to load current proportionality, can be used according to the application i.e., load-current compensation or loadcurrent regulation.
