HSDL-9001 Miniature Surface-Mount Ambient Light Photo Diode Data Sheet The HSDL-9001 is a low cost analog-output ambient light photo diode in lowest cost miniature Quad-FlatNo Lead QFN lead-free surface mount package. It consists of a photodiode, which peaks in human luminosity curve at 550 nm. Hence, it provides an excellent responsivity that is close to the response of human eyes, as shown in figure It provides a design-alternative to the HSDL-9000 digital-output ambient light photo sensor with infinite ambient light detection threshold control. Both the HSDL-9000 and HSDL-9001 are ideal for applications in which the measurement of ambient light is used to control display backlighting. Mobile appliances such as the mobile phones and PDAs that draw heavy current from the display backlighting will benefit from incorporating the HSDL-9000 and HSDL-9001 in their designs to reduce the power consumption significantly. Features • Excellent responsivity which peaks in the human luminosity curve at 550 nm Close responsivity to the human eye • Miniature QFN surface-mount package Height mm Width mm Depth mm • Infinite ambient light detection threshold control • Guaranteed temperature performance to 85°C • VCC supply to V • Lead-free and RoHS Compliant Applications • Detection of ambient light to control display backlighting Mobile devices mobile phones, PDAs Computing devices notebooks, webpads Consumer devices TVs, video cameras, digital still cameras • Daylight and artificial light exposed devices Application Support Information The Application Engineering Group is available to assist you with the application design associated with HSDL-9001 Ordering Information Part Number HSDL-9001 Packaging Type Tape and Reel infrared transceiver module.
