ELECTRICAL CHARACTERISTICS:
APPLICATION INFORMATION
Figure 1 shows the rectification and detection scheme
used in the UC1727 to derive both power and signal infor-
mation from the input waveform. V

EE
is generated by
peak detecting the input signal via the internal bridge rec-
tifier and storing it on external capacitors. COM is gener-
ated by an internal amplifier that maintains PV
CC
-COM =
16.5V.
Signal detection is performed by the internal hysteresis
comparator which senses the polarity of the input signal
as shown in Figure 2. This is accomplished by setting (or
resetting) the comparator only if the input signal exceeds
0.95

. In some cases it may be necessary to
add a damping resistor across the transformer secondary
to minimize ringing and eliminate false triggering of the
hysteresis comparator as shown in Figure 3.
