• Integrated modules: infrared emitter (IRED),

proximity sensor (PD), and signal conditioning IC

• Interrupt function

• Supply voltage range V

: 2.5 V to 3.6 V

• Supply voltage range IR anode: 2.5 V to 5 V

• Communication via I

C interface

•I

C bus H-level range: 1.7 V to 5 V

• Floor life: 72 h, MSL 4, according to J-STD-020

• Low stand by current consumption: 1.5 μA

• Material categorization: for definitions of compliance

please see www.vishay.com/doc?99912

PROXIMITY FUNCTION

• Built-in infrared emitter and photo-pin-diode for proximity

function

• 16 bit effective resolution for proximity detection range

ensures excellent cross talk immunity

• Programmable LED drive current from 10 mA to 200 mA in

10 mA steps

• Excellent ambient light suppression by signal modulation

• Proximity distance up to 200 mm
