Title: Current limit circuit and output circuit equipped therewith
Inventor: YOSHIDA MITSURU
IPC: G01R19/165
Filed: 2002-08-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide a current limit circuit capable of widening the application range of load without modifying an output circuit equipped with an overcurrent limit circuit.  <P>SOLUTION: Since the limit current level of an output transistor is increased as the output voltage from an output MOS transistor decreases, the area where a load curve does not intersect a current limit line is widened and thereby the load range available without lowering the short circuit resistance of load can be widened. More specifically, output voltage from the output transistor is monitored and input voltage to the output transistor is clamped at a different level depending on the output voltage level.  <P>COPYRIGHT: (C)2004,JPO
