SI1143 - PROXIMITY/AMBIENT LIGHT SENSOR IC

General Description

The Si1141/42/43 is a low-power, reflectance-based, infrared proximity and ambient light sensor with I2C digital interface and programmable-event interrupt output.

Key Features

  • Pin Assignments.
  • QuickSense™ integrated infrared proximity detector.
  • Proximity detection adjustable from under 1 cm to over 1 m.
  • Three independent LED drivers.
  • 15 current settings from 5.6 mA to 360 mA for each LED driver.
  • 25.6 µs LED driver pulse width.
  • 500 mm proximity range with single pulse (2.5 klx).
  • Operates at up to 128 klx (direct sunlight).
  • Minimum reflectance sensitivity < 1 µW/cm2.
