(u2481b / u2482b) automotive lamp outage monitor.
D Extremely low comparator thresholds of typically 3.5 mV D Internal compensation for copper shunts D Internal compensation for voltage-dependent bulb characteristic D Co.
Both ICs can be used in any kind of vehicle with a 12 V supply. It is sufficient to insert small resistors into the lamp.
The U2481B and the U2482B multicomparator circuits are designed to monitor automotive illumination by sensing the voltage drop across shunt resistors. Provided with extremely low comparator thresholds, these ICs can be used together as a chip set to .
