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.
• 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.
