U210B1
Phase Control Circuit–Load Current Feedback Applications
Description
The interated circuit, U210B1, is designed as a phase-
control 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 load-
current regulation.
