Description
The NOA3302 combines an advanced digital proximity sensor and LED driver with an ambient light sensor (ALS) and tri−mode I2C interface with interrupt capability in an integrated monolithic device. Multiple power management features and very low active sensing power consumption directly address the power requirements of battery operated mobile phones and mobile internet devices.

FEATUREs
• Proximity Sensor, LED driver and ALS in One Device
• Very Low Power Consumption
   ♦ Stand−by Current 5 A (monitoring I2C interface only,
      VDD = 3 V)
   ♦ ALS Operational Current 50 A
   ♦ Proximity Sensing Average Operational Current 100 A
   ♦ Average LED Sink Current 75 A

Additional Features
• Programmable interrupt function including independent
   upper and lower threshold detection or threshold based
   hysteresis for proximity and or ALS
• Proximity persistence feature reduces interrupts by
   providing hysteresis to filter fast transients such as
   camera flash
• Automatic power down after single measurement or
   continuous measurements with programmable interval
   time for both ALS and PS function
• Wide operating voltage range (2.3 V to 3.6 V)
• Wide operating temperature range (−40°C to 80°C)
• I2C serial communication port
   ♦ Standard mode – 100 kHz
   ♦ Fast mode – 400 kHz
   ♦ High speed mode – 3.4 MHz
• No external components required except the IR LED
   and power supply Decoupling Caps
• 8−lead CUDFN 2.0 x 2.0 x 0.6 mm clear package
• These Devices are Pb−Free, Halogen Free/BFR Free
   and are RoHS Compliant

APPLICATIONs
• Senses human presence in terms of distance and senses
   ambient light conditions, saving display power in
   applications such as:
   ♦ Smart phones, mobile internet devices, MP3 players,
      GPS
   ♦ Mobile device displays and backlit keypads
