FN6485.3
Light-to-Digital Output Sensor with High
Sensitivity, Gain Selection, Interrupt
Function and I 2 C Interface
The ISL29013 is an integrated light sensor with I 2 C (SMBus
Compatible) interface. It has an internal signed15-bit
integrating type ADC designed based on the charge-
balancing A/D conversion technique. This ADC is capable of
rejecting 50Hz and 60Hz flicker caused by artificial light
sources. The lux range select feature allows the user to
program the lux range for optimized counts/lux.
In normal operation, power consumption is typically 250μA.
Furthermore, a power-down mode can be controlled by
software via the I 2 C interface, reducing power consumption
to less than 1μA.
The ISL29013 supports a hardware interrupt that remains
asserted low until the host clears it through I 2 C interface.
Designed to operate on supplies from 2.5V to 3.3V, the
ISL29013 is specified for operation over the -40°C to +85°C
ambient temperature range.

NOTES:
1. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special
Pb-free material sets; molding compounds/die attach materials
and 100% matte tin plate - e3 termination finish, which is RoHS
compliant and compatible with both SnPb and Pb-free soldering
operations. Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the
Pb-free requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), please see device
information page for ISL29013 . For more information on MSL
please see tech brief TB466 .
