com U210B1 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.
