Overview
U6433B Flasher, 18-mW Shunt, Frequency Doubling Disabling 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 be used for a hazard switch which bypasses the external shunt resistor to disable the frequency doubling.
This feature 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.
and low saturation voltage Features D Temperature and voltage compensated frequency D Warning indication of lamp failure by means of frequency doubling can be disabled D Voltage dependence of the car indicator lamps compensated for lamp failure D Relay output with high current carrying capacity D D D D Minimum lamp load for flasher operation Load-dump protection Very low susceptib...
