| Agilent HSDL-9000 Miniature Surface-Mount Ambient Light Photo Sensor Data Sheet Description The HSDL-9000 is a low cost, digital-output ambient light photo sensor in miniature industrystandard PLCC lead-free surfacemount package. It incorporates 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 With the options of three digital levels and an analog Gain Control pin to fine tune the three threshold levels to achieve better sensitivity control, the HSDL9000 is ideal for applications in which the measurement of ambient light is used to control display backlighting. Mobile appliances such as mobile phones and PDAs that draw heavy current from the display backlighting will benefit from incorporating the HSDL-9000 in their designs to reduce the power consumption significantly. • Excellent responsivity which peaks in the human luminosity curve at 550 nm Close responsivity to the human eye • Miniature PLCC surface-mount package Height mm Width mm Depth mm • Ease of design with digital output Integrated photodiode and analog to digital output circuitry • Enable fine control of the backlight intensity with adjustable sensitivity control 3 digital levels An Analog Gain Control • Minimum power consumption 30 µA typical idle standby current <10 nA typical shutdown current • Guaranteed temperature performance to 85°C • VCC V • Lead-free package • Low cost • Detection of ambient light to control display backlighting Mobile devices mobile phones, PDAs Automotive dashboard Consumer appliances audio sets • Daylight and artificial light exposed devices Ordering Information Part Number HSDL-9000 Packaging Type Tape and Reel Package 6-lead PLCC with Top Transparent Epoxy Surface Application Circuit For HSDL-9000 Ambient Light Photo Sensor 1 VCC R1 5 AGain Quantity 1500 HSDL-9000 ANALOG TO DIGITAL CIRCUITRY DOUT 6 Figure Functional block diagram of HSDL-9000.
