Title: Overcurrent detecting circuit
Inventor: FUKAMI IKUO
IPC: H01L27/04
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To suppress chip area and besides, enable plural drains mounted on one chip to be electrically independent by providing an overcurrent detecting circuit with a sense terminal which takes out the voltage drop of the drain resistor of a MOSFET for load drive, and a voltage comparator which compares the voltage drop with reference voltage. SOLUTION: In an overcurrent circuit, one end of a drain terminal 13 is utilized as a sense terminal 16. Moreover, a drain resistor 12 is constituted in a region which goes in the direction of a channel, with, especially, the drain terminal of a current course lying between the drain terminal and the source terminal of a MOSFET 3 as its starting point. MOSFET 3 is connected with a positive power source wiring 1 through the drain resistor 12, and the gate is connected to a gate drive circuit 5, and the source is connected to load 4 through an output end 8. When the MOSFET 3 is turned on by the gate drive circuit 5, a current flows by the potential difference between the positive power source and the negative power source.  The voltage drop proportionate to the current at this time appears in the drain resistor 12, and a voltage comparator 6 performs the comparison between this voltage drop ad the reference voltage 7.
