Pin Descriptions
PIN NUMBER PIN NAME
DESCRIPTION
1
VDD Positive supply; connect this pin to a 2.25V to
3.63V supply
2
GND Ground pin
3
R_EXT External resistor pin for ADC reference;
connect this pin to ground through a (nominal)
499kΩ resistor.
4
INT Interrupt pin; low for interrupt alarming. INT
pin is open drain. INT remains asserted until
the interrupt flag status bit is reset.
5
SCL I²C serial clock. This line can be pulled from
1.7V to above V_DD, 3.63V max.
6
SDA I²C serial data. This line can be pulled from
1.7V to above V_DD, 3.63V max.
PAD Exposed pad connected to ground or
electrically isolated

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 ISL29023. For more information on MSL please see tech brief TB477.
