Title: Constant current circuit
Inventor: HIRUMOTO YASUYUKI
IPC: G05F3/24
Filed: 2003-01-20
Abstract: <P>PROBLEM TO BE SOLVED: To obtain a constant current circuit that is provided with a circuit which stably puts restrictions on a short-circuit current even if a source voltage changes when an external resistor short-circuits.  <P>SOLUTION: When both sides of the external resistor 5 are in a short-circuit state by a short-circuit or the like, the short-circuit current IS flows toward an earth from a regulator terminal 4. The short-circuit current IS is determined by a reference voltage in a current restriction circuit 10, the gate-source voltage of an NMOS transistor 11, a resistance value of a current limiting resistor element 12 and a source-drain voltage of an NMOS transistor 21 in a regulator circuit 2. Instantly, the short-circuit current can be limited to a small size by adjusting the reference voltage in the current restriction circuit 10 and the resistance value of the current limiting resistor element 12. Further, the magnitude of the short-circuit current IS has no relation with a source voltage applied to the source terminal 3 of a current mirror circuit 1.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
