KEY FEATURES

. Proximity detector

. From under 1 cm, to 50 cm without

additional lensing.

. From under 1 cm, to 200 cm with

additional lensing (e.g., 5 mm

hemispherical lens as in our EVB).

. Up to three independent LED drivers.

. 30 current settings from 5.6 mA to 360

mA for each LED driver.

. Operates in direct sunlight with optional

on-die 940 nm passband filter.

. On die 940 bandpass filter that rejects

unwanted visible light and IR from

daylight and other sources (Si115x-

AB09/AB9X).

. Ambient light sensor

. <100 mlx resolution possible, allowing

operation under dark glass.

. Up to 128 klx dynamic range possible

across two ADC range settings.

. Industry’s lowest power consumption

. 1.62 to 3.6 V supply voltage.

. 9 μA average current (LED pulsed 24.4

μs every 800 ms at 180 mA plus 3 μA

Si115x supply).

. <500 nA standby current.

. 24.4 μs LED “on” time keeps total power

consumption duty cycle low without

compromising performance or noise

community.

. Internal and external wake support.

. Built-in voltage supply monitor and

power-on reset controller.
