Filed: 2002-03-25
Abstract: <P>PROBLEM TO BE SOLVED: To detect an overcurrent of a load which causes a rush current when current flowing is started.  <P>SOLUTION: A first current source circuit 19 receives a load driving signal, generates a current pulse similar to an impulse response of a time-lag of first order circuit, converts the pulse to a voltage waveform by a first resistor R4 through a first and a second current mirror circuits 11, 17, and makes the voltage waveform a threshold voltage for overcurrent detection. A first and a second switching elements Q5, Q6 are so formed that a load current is shared by a constant ratio. A second resistor R5 connected in series with the second switching element Q6 generates a voltage proportional to the load current, and detects the overcurrent by comparing the voltage with the threshold voltage.  <P>COPYRIGHT: (C)2004,JPO
