IL7101
GROUND FAULT INTERRUPTER EARTH
LEAKAGE CURRENT DETECTOR
IL7101
Description
The IL7101N/D 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 connect to the
secondary node of zero current transformer.
The level comparator generates high level when earth leakage current is
greater than some level.
Feature

• 100V/200V Common Built-in Voltage Regulator
• High Gain Differential Amplifier
• High Input Sensitivity
• Minimum External Parts
• Large Surge Margin
• Wide Operating Temperature Range (TА= -40 to 85°C)

Typical Application
Supply voltage circuit is connected as a previous diagram. Please decide constants R1, R2, C4, and C5 of a
filter in order to keep at least 12V in Vs, when normal supply current flows.
In this case, please connect C4 (more than 1 ㎌) and C2 (less than 1 ㎌). ZCT and load resistance RL of ZCT
are connected between input pin① and ②. In this case protective resistance (R3=100Ω) must be insulted.
Sensitivity current is regulated by RL, and output of amplifier shows in pin④. External capacitor C1 between
pin④ and GND is used for noise removal.
When large current is grounded in the primary side (AC line) of ZCT, the wave form in the secondary side
of ZCT is distorted and some signals doesn’t appear in the output of amplifier. So please connect a varistor or
a diode (2pcs.) to ZCT in parallel.
Latch circuit is used to inspect the output level of amplifier and to supply gate current on the external SCR.
When input pin becomes more than 1.1V (Typ.) latch circuit operates and supply gate current in the gate of
SCR connected to the output pin⑦.
Pin⑥ can be used in the open state, but please connect capacitor (about 0.047 ㎌) between pin⑥ and ⑦.
Capacitor C6 between pin① and GND is used to remove noise and is about 0.047 ㎌.
