Abstract
The present invention relates to an IC circuit. In an embodiment, an IC circuit includes: an RT terminal connected to an external; a current mirroring unit conducting a channel current between internal voltage power and the RT terminal and generating an internal reference current mirrored with the channel current; a negative feedback unit receiving the internal reference current, equalizing voltages of an RT terminal connection terminal and an internal reference current output terminal of the current mirroring unit to make the internal reference current constant, and providing the internal reference current inside the IC circuit; and an IC state indicating unit having a transistor, which operates complementarily with the current mirroring unit, connected between the RT terminal and a ground and providing the state of an IC or a system to the RT terminal by being linked with the complementary operation of the current mirroring unit.
