Title: Light detecting ic
Inventor: OKAMURA KOICHI
IPC: H01L33/00
Filed: 1990-11-27
Abstract: PURPOSE:To stabilize the light emitting output of an LED without using an external element by incorporating the constant current circuit connected to the LED in a light detecting IC and controlling the current of the LED by said circuit. CONSTITUTION:A constant current circuit is constituted of voltage dividing resistors 16a, 16b, an operational amplifier 17, a transistor 18 and a resistor 19 to drive an LED. When the voltage VB of a power supply is applied, a current I3 flows to LED 3 and voltage VD is generated in the resistor 19 to be applied to the operational amplifier 17. Further, the operational amplifier 17 outputs the voltage corresponding to the difference between the voltage VD and reference voltage Vr to drive a transistor 18. When the resistance value of the resistor 19 is set to R19, I3=Vr/R19 is formed and, since the irregularity of resistance can be neglected, the current I3 flowing to the LED 3 becomes almost constant. A photodetector 12 is arranged in opposed relation to the LED 3 and detects the light from the LED 3 to output voltage V0. By this method, the stable light emitting output and output voltage V0 of the LED can be obtained.
