PHOTO IC
Light modulation photo IC
S4282-51, S6809, S6846, S6986, S7136/-10, S10053
Fewer detection errors even under disturbance background light
These light modulation photo ICs were developed for optical synchronous detection under disturbance background light. A photodiode,
preamplifier, comparator, oscillator, LED driver and signal processing circuit, etc. are all integrated on a monolithic photo IC chip. Optical
synchronous type photoreflectors and photointerrupters, which less susceptible to disturbance background light, can be easily configured by just
connecting an external LED to this photo IC. Our unique circuit design achieves an allowable background light level of 10000 lx Typ. (S4282-51,
S6986, S10053) and a minimum detection level of 0.2 µW/mm2 Typ. (S6809, S6846, S7136/-10).
Features
l Large allowable background light level
S4282-51, S6986, S10053: 10000 lx Typ.
S6809, S6846, S7136/-10 : 3000 lx Typ.
l Minimum detection level
S4282-51, S6986, S10053: 0.7 µW/mm2 Typ.
S6809, S6846, S7136/-10 : 0.2 µW/mm2 Typ.
l Digital output (Output appears “L” by light input.)
l Small hysteresis (S6809)
l Small SMD package (S10053)
Applications
l Paper detection in office machine (copiers, fax machines, etc.)
l Optical switch
s Absolute maximum ratings (Ta=25 °C)
