U6433B - Flasher/ 18-m Shunt/ Frequency Doubling Disabling

TEMIC Semiconductors

Datasheet Details

The design of the U6433B is mainly based on the good results of U6043B in terms of EMC (Electro Magnetic Capability) and protection

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 indi.
