... Very Low Susceptibility to EMI • Protection According to ISO/TR 7637/1 Level 4 Description The bipolar integrated circuit U6043B is used in relay-controlled automotive flashers where a high level EMC is required. Lamp outage is indicated by frequency doubling during hazard warning as well as direction mode. Flasher IC with 18-mW Shunt U6043B 4726A– ...

... Sense Pin 7, Lamp Outage Detection U6043B 4 The U6043B is protected against damage in case of battery reversal via resistor R ground (-31). An integrated protection circuit together with external resistances R R limits the current pulses in the IC. 4 The arrangement of the supply connections to Pin 2 (and 6) must ensure that on the connection printed circuit board (PCB), the resistance of V than that to Pin 2 ...
