TEPT4400

www.DataSheet4U.com TEPT4400 Vishay Semiconductors Ambient Light Sensor Description TEPT4400, photo transistor for ambient light sensor application, plays a key role in power savings strategies by controlling LCD display intensity and keypad backlighting of mobile devices and in industrial on/offlighting operation. It is sensitive to visible light much like the human eye and has peak sensitivity at 570 nm. TEPT4400 is packaged in a T 1" package. 94 8396 Features High sensivity, IPCE = 200 µA (EV = 100 lx) Adapted to human eye responsivity Wide angle of half sensitivity ϕ = ± 30° e4 T 1" package (3 mm) Lead (Pb)-free component in accordance with RoHS 2002/95/EC and WEEE 2002/96/EC Applications Ambient light sensor for control of display backlight dimming in LCD displays and keypad backlighting of mobile devices and in industrial on/off-lighting operation.
