Integrated Digital Ambient Light Sensor
and Proximity Sensor
The ISL29015 is an integrated ambient and infrared light to
digital converter with a built-in IR LED driver and I
interface. This device provides not only ambient light sensing
to allow robust backlight/display brightness control but also
infrared sensing to allow proximity estimation.
For ambient light sensing, an internal 16-bit ADC has been
designed based on the charge-balancing A/D conversion
technique. The ADC conversion time is nominally 100ms
and is user adjustable from 25µs to 100ms depends on
oscillator frequency and ADC resolution. This ADC is
capable of rejecting 50Hz and 60Hz flicker noise caused by
artificial light sources. The lux-range-select feature allows
users to program the lux range for optimized counts/lux.
For proximity sensing, the ADC is used to digitize the output
signal from the photodiode array when the internal IR LED
driver is turned on and off for the programmed time periods
under user-selected modulation frequency to drive the
external IR LED. As this proximity sensor employs a noise
cancellation scheme to highly reject unwanted IR noise, the
digital output of proximity sensing decreases with distance.
The driver output current is user selectable up to 100mA to
drive different types of IR emitters LEDs.
Six different modes of operation can be selected via the I
interface: Programmable ALS once with auto power-down,
programmable IR sensing once, programmable proximity
sensing once, programmable continuous ALS sensing,
programmable continuous IR sensing and programmable
continuous proximity sensing. The programmable one-time
operation modes greatly reduce power because an
immediate automatic shutdown reduces overall supply
current less than 1µA.
Designed to operate on supplies from 2.25V to 3.3V, the
ISL29015 is specified for operation over the -40°C to +85°C
ambient temperature range. It is packaged in a clear, Pb-free
6 Ld ODFN package.
