DESCRIPTION
The design of 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 susceptibility to EMI y1W Protection according to ISO/TR 7637/1 level 4 Ordering Information Extended Type Number U6433B–FP Package SO8 Remarks Block Diagram 6 G5 2 + K1 – + K4 – V S – 8 mV 4 + K5 – G2 VS – 4 V K2 V S – 49 mV VS C1 4.7 mF D1 23 V 82 k W 5 R1 G4 K3 49 a V S–6 V 3 7 VS – 8 V 8 1 Shunt VS R3 18 m R4 W R2 1.5 k W 470 W PL>1 W 94 9289 Figure 1.
