1. Add “-T” suffix for tape and reel. Please refer to
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach
3. For Moisture Sensitivity Level (MSL), please see device information page for
ISL62881C ISL62881D
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.
MSL please see techbrief TB363.

PART MARKING
Open drain output to enable system PLL clock. It goes low 13 switching cycles after
V
Power-Good open-drain output indicating when the regulator is able to supply
regulated voltage. Pull up externally with a 680Ω resistor to VCCP or 1.9kΩ to 3.3V.
A resistor to GND sets internal current reference. A 147kΩ resistor sets the controller
for CPU core application and a 47kΩ resistor sets the controller for GPU core
application.
Thermal overload output indicator.
Thermistor input to VR_TT# circuit.
Signal common of the IC. Unless otherwise stated, signals are referenced to the GND
pin.
