Light-to-Digital Output Sensor with High Sensitivity, Gain Selection, Interrupt

Function and I2C Interface

Rev 3.00

November 11, 2011

The ISL29013 is an integrated light sensor with I2C (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 I2C interface, reducing power consumption

to less than 1µA.

The ISL29013 supports a hardware interrupt that remains

asserted low until the host clears it through I2C 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.
