Title: Overcurrent detection circuit
Inventor: MEJIKA KENICHI
IPC: H03F1/52
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To obtain an overcurrent detection circuit which functions reliably regardless of the load impedance while lowering the detection level upon short circuit of the load. SOLUTION: Resistance of a resistor 51 is set such that a transistor 53 is turned on with a current lower than a maximum load current. A voltage corresponding to the load current is generated in a load 30. Resistance of resistors 54, 56 is set such that the voltage level at a terminal 60a of a control section 60 exceeds a threshold voltage Vth when the voltage between the terminals of the load 30 (emitter voltage of the transistor 53) exceeds a voltage level Vk. Since the transistor 53 is turned on before a maximum load current flows and the voltage of the load 30 is substantially '0' when the load is short- circuited, the voltage level at the terminal 60a is lower than the voltage Vth.  When the impedance of the load 30 is high, the voltage of the load 30 is higher than the voltage level Vk even if the transistor 53 is turned on and the voltage level at the terminal 60a is higher than the voltage Vth. Consequently, an overcurrent can be detected based on the voltage level at the terminal 60a.
