U2480B Automotive Lamp Outage Monitor Description The IC U2480B is designed for individual monitoring of 11 lamps in automobiles.
Three double comparators and five single comparators, which can be optionally interconnected, permit realization of many monitoring variants.
An integrated latch is available to memorize the outage of indicator or brake lamps.
Features D 10 mV comparator thresholds D Temperature compensated D Voltage characteristic of the lamps is taken into D D account Input voltage range up to 23 V independent of supply Typical input currents 25 mA, so that protective resistors can be connected in series D Internal protection measures for pulses according to ISO TR 7637/1 D E...
