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 ISL6363. For more information on MSL please see techbrief TB363.

DESCRIPTION
Common ground signal of the IC. Unless otherwise stated, signals are referenced to the GND pin. The pad should also be
used as the thermal pad for heat dissipation.
This pin is a placeholder for potential future functionality. This pin can be left floating.
Power-good open-drain output indicating when VR1 is able to supply a regulated voltage. Pull-up externally with a 680Ω
resistor to +5V or 1kΩ to +3.3V.
+5V bias supply pin. Connect a high quality 0.1µF capacitor from this pin to GND and place it as close to the pin as possible.
A small resistor (2.2Ω for example) between the +5V supply and the decoupling capacitor is recommended.
VR1 current sense input pins for current monitoring, droop current and overcurrent detection.
VR1 phase 1 current sense input pin for phase current balancing.
VR1 phase 2 current sense input pin for phase current balancing.
VR1 phase 3 current sense input pin for phase current balancing.
