Si115x Data Sheet

Proximity/Ambient Light Sensor IC with I C Interface

KEY FEATURES

The Si115x-AB00/AB09/AB9x is an ambient light sensor, proximity, and gesture detector

with I2C digital interface and programmable-event interrupt output.

• Proximity detector

• From under 1 cm, to 50 cm without

additional lensing.

This touchless sensor IC includes dual 23-bit analog-to-digital converters, an integrated

high-sensitivity array of visible and infrared photodiodes, a digital signal processor, and

up to three integrated LED drivers with programmable drive levels. The Si115x offers ex-

cellent performance under a wide dynamic range and a variety of light sources, including

direct sunlight. The Si115x can also work under dark glass covers. The photodiode re-

sponse and associated digital conversion circuitry provide excellent immunity to artificial

light flicker noise and natural light flutter noise. With two or more LEDs, the Si115x is

capable of supporting multiple-axis proximity motion detection. The Si115x is provided in

a 10-lead 2x2 mm DFN package or in a 10-lead 2.9x4.9 mm LGA module with integra-

ted LED, and is capable of operation from 1.62 to 3.6 V over the –40 to +85 °C tempera-

ture range.

• 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).

VDD

Internal Osc.

Regulator

• Ambient light sensor

• <100 mlx resolution possible, allowing

operation under dark glass.

ALS Photodiodes

• Up to 128 klx dynamic range possible

across two ADC range settings.

Drivers

• 9 μA average current (LED pulsed 24.4

μs every 800 ms at 180 mA plus 3 μA

Si115x supply).

and

• <500 nA standby current.

(Filter Only in

AB09 & AB9X

versions)

Control

• 24.4 μs LED “on” time keeps total power

consumption duty cycle low without

compromising performance or noise

community.

• Internal and external wake support.

INT

• Built-in voltage supply monitor and

power-on reset controller.

APPLICATIONS

I2C addr sel

• Wearables

• Handsets

Pull up to VDD with 47 kOhm resistor to select primary I2C address (0x53),

• Display backlighting control

• Consumer electronics

or down to GND for alt I2C address 0x52. LED2 driving capabilities only

available on Si1152 and Si1153.

** Pull up to VDD with 47 kOhm resistor. LED3 driving capabilities only

available on Si1153.
