EARTH LEAKAGE CURRENT DETECTOR
EARTH LEAKAGE
CURRENT DETECTOR IC
BD9582F, BD9582N
●General Description
BD9582F/BD9582N integrates leakage detector and
amplifier.
Especially, it is suitable for high sensitivity and a high-
speed operation use, and since the operating temperature
range is wide, it can be used for various uses.
