Flasher, 18-m
Description
The design of the U6433B is mainly based on the good
results of U6043B in terms of EMC (Electro Magnetic
Capability) and protection features. It includes an
additional 8-mV comparator and a logical connection
with the frequency doubling stage. This combination can

shunt resistor to disable the frequency doubling. This fea-
ture can be useful in the US automotive industry. During
direction mode the U6433B works like other flashers, i.e.,
frequency doubling in the case of lamp outage.
