0V to 5.
5V ●Operating Temperature -40 to 105 ●Built-in High Precision ADC 14-Bit ●Sinc3 Digital Filter -3dB Frequency = 150Hz ●Internal Power Supply VREG=3.
3V VCOM=1.
65V ●Earth Leakage Detector Condition (TMD) Type A / Type AC switchable ●Control Circuit Earth Leakage Detector Condition (TMD) Sampling Counter (SCRT) ●Package DMP8 ■GENERAL DESCRIPTION NJU9102 is a digital detector IC for earth leakage current breaker.
The built-in ADC converts from an analog signal from ZCT (Zero-phase-sequence Current Transformer) to digital data, and processes digital data based on an earth leakage current detector condition.
As a result of data processing, NJU9102 outputs a one-shot pulse on SCRT terminal when an analog signal is judged to a leakage condition, and turns on an external thyristor.
