P6448

The P6448 is designed as a photoreflector consisting of a light modulation photo IC and an infrared LED, etc. The light modulation photo IC allows reliable operation even under background disturbance light. P6448's typical applications is reflective optical switches.

P6448 has three features. (1)Compact size (35x10x17mm). (2)Detection distance 30cm typ. (3)Allowable background light level: 2000lx min. Those are all the main features.

Some absolute maximum ratings of P6448 have been concluded into several points as follow. (1)Its supply voltage would be from -0.5V to 7V. (2)Its output current would be 50mA. (3)Its output voltage would be from -0.5V to 12V. (4)Its operating temperature range would be from -20°C to 60°C. (5)Its storage temperature range would be from -30°C to 85°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of P6448 are concluded as follow. (1)Its supply voltage would be min 4.75V and max 5.25V. (2)Its current consumption would be max 11mA for Vo open, no emission and typ 80mA and max 200mA during LED emission. (3)Its low level output voltage would be typ 0.15V and max 0.4V. (4)Its high level output voltage would be min 4.5V. (5)Its maximum detectable distance would be min 200mm and typ 300mm reflective paper with reflectivity of 90%. (6)Emission light pulse cycle would be typ 130us. (7)Its emission light pulse width would be typ 8us. (8)Its H to L propagation delay time would be max 1ms. (9)Its L to H propagation delay time would be max 1ms. (10)Its allowable background light level would be min 2000lx. (11)Its hysteresis would be min 0.45 and typ 0.65 and max 0.95. And so on. At present we have not got so much information about this IC and we would try hard to get more information about it.
