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 NiPdAu plate

- e4 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 ISL29018. For more information on MSL please see techbrief TB477.

DESCRIPTION

1

VDDD

Positive digital supply: 2.25V to 3.63V.

2

VDDA

Positive analog supply: 2.25V to 3.63V, VDDA and VDDD should be externally shorted.

3

GND

Ground. The thermal pad is also connected to the GND pin.

4

REXT

External resistor pin setting the internal reference current and the conversion time. 499k

Ω with 1% tolerance resistor is

recommended.

5SCL

6SDA

7INT

Interrupt pin; LO for interrupt/alarming. The INT pin is an open drain.

8

IRDR

IR LED driver pin connecting to the anode of the external IR LED. The source current of the IR LED driver can be

Exposed pad connected to ground or electrically isolated.
