Title: Switching device
Inventor: FUSHIMI IKUO
IPC: H03K17/60
Filed: 1985-02-08
Abstract: PURPOSE:To attain sure switching operation even when a current due to noise or the like is caused or a minute current such as a leak current exists at an input terminal by applying a current to a load circuit only when the quality of the current flowing to the input terminal reaches a set threshold value or larger than the value. CONSTITUTION:When the current I exceeds the threshold value Ith, the relation between collector currents of transistors (TRs) Q3, Q4 is in the state of Ic3<Ic4. Since the collector current of a TR Q2 biased by a TR Q1 is equal to the Ic3, the collector potential of the TR Q4 is decreased, a TR Q6 is turned on and a current is fed to a load circuit 3 from a power supply 1. The threshold value Ith is set to a desired level by deciding the emitter area ratio (n) and the resistance value of a resistor R2.
