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.

Figure 17. Load current regulation with soft start
Current regulation is achieved by the integrated opera-
tional amplifier as P1-controller (R7, C5, C6). Inverted
input (Pin 7) of the operational amplifier is directly con-
nected at C3 with load current proportional test signal
(actual value).
Desired value is obtained with the help of potentiometer
at Pin 8.
