IL7101N
EARTH LEAKAGE
CURRENT DETECTOR
Description
The IL7101N is designed for use in earth leakage circuit
interrupters for operation directly oft the AC Line in breakers.
It contains pre regulator, main regulator, after regulator,
differential amplifier, level comparator, latch circuit. The input
in the differential amplifier is connect to the secondary node of
zero current transformer. The level comparator generates high
level when earth leakage current is greater than some level.
