- Miniature PLCC surface-mount package Height – 1.1 mm Width – 4.0 mm Depth – 3.2 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 –25°C to 85°C
- 2.7 ≤ V CC ≤ 3.6 V
- Lead-free package
- Low cost
Applications
- 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 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 HSDL- 9000 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 back- lighting will benefit from incorporating the HSDL-9000 in their designs to reduce the power consumption significantly.
