Description
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 build an entire lamp monitor system.
Features
- 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 Comparator input voltage may exceed supply voltage D Internal protection measures for pulses according to ISO TR 7637/1 D ESD according to MIL-SID-883 C test method 3015.7.
- Human body model: 4 kV.
- Machine model: 200 V EMI protection (TEM cell up to 100 V/m)
Benefits
D Extremely low threshold voltage gives low vo.
