FUNCTION
Adjustable Sink Current Output Pin. The current that sinks into the OUT pin is equal to the DAC setting times
the maximum adjustable sink current divided by 128. See SET pin function description for the maximum
adjustable sink current setting.
High-Voltage Analog Supply. Bypass to GND with 0.1µF capacitor.
Pull-Down Write Protect. Active Low. To enable programming, connect to 0.7*V_DD supply or greater. The WP pin is
designed for static control. It has an internal pull-down current sink. To avoid the possibly overwriting the
EEPROM contents, no frequency above 1Hz should be applied to this input. Care should be taken to avoid
any glitches on the input. When removing or applying mechanical jumpers, always ensure the V_DD power is
off. A high to low transition on the WP pin results in the register contents being loaded with EEPROM data.
Ground connection
Digital power supply input. Bypass to GND with 0.1µF capacitor.
I²C Serial Data Input and Output
I²C Clock Input
Maximum Sink Current Adjustment Point. Connect a resistor from SET to GND to set the maximum
adjustable sink current of the OUT pin. The maximum adjustable sink current is equal to (AV_DD/20) divided
by RSET.
Thermal pad. Electrically connected to GND. Connect to ground plane on PCB to maximize thermal
performance.

NOTES:
1. Add “-T*” suffix for tape and reel. 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 plus anneal (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 ISL45041. For more information on MSL, please see Technical Brief
TB363.
