ZGFI7101 Earth Leakage Detector
Product Specification
1. General Description
The ZGFI7101 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 amplifier is connected to the secondary node of zero
current transformer. The level comparator generates high level when earth leakage current is greater than
some level.
2. Features
Low Power consumption (PD = 5mW) 100V/ 200V
100V/200V Common Built-in Voltage Regulator
High Gain Differential Amplifier
High Input Sensitivity (VT = 13.5mV Typ.)
Minimum External Parts
Large Surge Margin
Wide Operating Temperature Range (TA = -30 to 85Ԩ)
High Noise Immunity
GL7101,M54122 pin compatible
