Features
1. Description
The design of the U6433B is similar to that of U6043B, both devices have the same
excellent EMC (Electro Magnetic Capability) and protection features. The U6433B
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 is especially
important with respect to the US automotive industry. During direction mode the
U6433B works like other flashers, that is, frequency doubling in the case of lamp
outage.
Temperature and Voltage Compensated Frequency
Warning Indication of Lamp Failure by Means of Frequency Doubling can be Disabled
Voltage Dependence of the Car Indicator Lamps Compensated for Lamp Failure
Relay Output with High Current Carrying Capacity and Low Saturation Voltage
Minimum Lamp Load for Flasher Operation
Load-dump Protection
Very Low Susceptibility to EMI
