Functional Pin Description
PGOOD - Power good open-drain output. Will be pulled up
externally by a 680Ω resistor to VCCP or 1.9kΩ to 3.3V.
PSI# - Low load current indicator input. When asserted low,
indicates a reduced load-current condition, and product goes
into single phase operation.
PGD_IN - Digital Input. When asserted high, indicates
VCCP and VCC_MCH voltages are within regulation.

RBIAS - 147K resistor to VSS sets internal current
reference.
VR_TT# - Thermal overload output indicator with open-drain
output. Over temperature pull-down resistance is 10Ω.
NTC - Thermistor input to VRTT# circuit and a 60µA current
source is connected internally to this pin.
