DESCRIPTION
The IL7101 is designed for use in earth leakage circuit
interrupters for operation directly off the AC Line in breakers.
It contains pre regulator, main regulator, after regulator, differential
amplifier, level comparator, latch circuit. The input in the differential
amp latch circuit. The input in the differential amplifier is connecting to
the secondary node of zero current transformer.
The level comparator generates high level when earth leakage
current is greater than some level.
