■GENERAL DESCRIPTION
NJU9102/A 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/A outputs a one-shot pulse
on SCRT terminal when an analog signal is judged to a
leakage condition, and turns on an external thyristor.
