KIA4210FV

SEMICONDUCTOR TECHNICAL DATA LAMP FAILURE INDICATOR. Function of this IC is used as a monitor for lamp failure in automobiles. Output is triggered as compare built-in reference voltage with the variance of lamp current by small value of resistance. High accuracy of the built-in comparator. (Can be easy to detect the opened line even one of any lamps is opened, because reference voltage is based on lamp current). Memorable the open status after detecting all the line such as stop lamp or others lamps and the delayed characteristic by the capacitance of outside let it possible to keep the memory in safty. 8 A 5 D P KIA4210FV BIPOLAR LINEAR INTEGRATED CIRCUIT H T L G Detectable the opened line of fuse of lamp. The output is designed for 0.3A driving ability and it is able to drive the lamp on purpose of various warnings. 1 4 DIM A B1 B2 D G H L P T MILLIMETERS _ 4.85 + 0.2 _ 3.94 + 0.2 _ 6.02 + 0.3 _ 0.4 + 0.1 0.15+0.1/-0.05 _ 1.63 + 0.2 _ 0.65 + 0.2 1.27 0.20+0.1/-0.05 B1 MAXIMUM RATINGS (Ta=25 CHARACTERISTIC Operating Voltage DC Supply Voltage Surge Supply Current Surge Input Voltage Output Current Power Dissipation Operating Temperature Storage Temperature ) RATING 18 24 200 65 300 240 -30 85 -55 150 CONDITION Rs=220 =100ms =100ms UNIT V V mA V mA mW SYMBOL VCC(opr) VCC(DC) ICC(S) VIN(S) IOL PD Topr Tstg BLOCK DIAGRAM Ref.
