SCRT OSC GND TMD VIN- VREG VDD VIN+ NJU9102/A Digital Earth Leakage Current Detector IC FEATURES GENERAL DESCRIPTION Power Supply VDD 4.0V to 5.5V NJU9102/A is a digital detector IC for earth leakage Operating Temperature -40 to 105 current breaker. Built-in High Precision ADC 14-Bit The built-in ADC converts from an analog signal from Sinc3 Digital Filter -3dB Frequency = 150Hz ZCT (Zero-phase-sequence Current Transformer) to Internal Power Supply V =3.3V digital data, and processes digital data based on an REG V =1.65V earth leakage current detector condition. As a result of COM Earth Leakage Detector Condition (TMD) data processing, NJU9102/A outputs a one-shot pulse Type A / Type AC switchable on SCRT terminal when an analog signal is judged to a Five times trip level detection leakage condition, and turns on an external thyristor.
