Description
The U2481B and the U2482B multicomparator circuits are designed to monitor automotive illumination by sensing the voltage drop across shunt resistors.
4 single comparators
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.
