Abstract
The present invention provides a semiconductor integrated circuit for detecting leakage current to determine whether an electric leakage occurs in an electric line based on an induced voltage input from a leakage current detection unitinstalled in the electric line, and an earth, leakage circuit breaker having the semiconductor integrated circuit. A semiconductor integrated circuitfor detecting leakage current includes: a signal amplification unitconfigured to amplify the induced voltage; an interruption determination unitconfigured to compare an output voltage output from the signal amplification unit with a preset reference voltage, and output an interruption signal for interrupting a power supply to the electric line; a flare current stabilization (FCS) circuitfor a signal amplification unit connected to the signal amplification unit; and a flare current stabilization (FCS) circuitfor an interruption determination unit connected to the interruption determination unit.
