U209B3/ U209B3–FP
Phase Control Circuit – Tacho Applications
Description:
The integrated circuit U209B3, is designed as a phase
control circuit in bipolar technology. It has also protection
circuit for the supply. Due to integration of many
functions, it leads to significant cost and space saving as
well as increased reliability. At the same time, it gives the
designer free hand to select varieties of regulators to
choose from and switching characteristics according to its
choice.

General Hints and Explanation of Terms
To ensure safe and trouble–free operation, the following
points should be taken into consideration when circuits
are being constructed or in the design of printed circuit
boards.
D The connecting lines from C2 to Pin 6 and Pin 2 should
be as short as possible, and the connection to Pin 2
should not carry any additional high current such as
the load current. When selecting C2, a low tempera-
ture coefficient is desirable.
D The common (earth) connections of the set–point gen-
erator, the tacho–generator and the final interference
suppression capacitor C4 of the f/V converter should
not carry load current.
D The tacho generator should be mounted without
influence by strong stray fields from the motor.
