Proximity detection requires only a single external IR LED. An internal LED driver can be configured to provide

a constant current sink of 12.5 mA, 25 mA, 50 mA or 100 mA of current. No external current limiting resistor is

required. The number of proximity LED pulses can be programmed from 1 to 255 pulses. Each pulse has a 14-

μs

period. This LED current coupled with the programmable number of pulses provides a 2000:1 contiguous

dynamic range.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 1: All voltages are with respect to GND.
