Operating Conditions
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Tj−TSD allowed during error conditions only. It is assumed that this maximum temperature condition does not occur more than 1 hour
2. Low qJA is obtained with 2S2P test board (2 signal − 2 plane). High qJA is obtained with double sideboard with minimum pad area and natural

Current limit programming pin. Connect a resistor between
INRUSH and VPORTN.
Classification current programming pin. Connect a resistor
between CLASS and VPORTN.
Detection pin. Connect a 24.9 kW resistor between DET and
VPORTP for a valid PD detection signature.
Negative input power. Connected to the source of the internal
pass−switch
DC−DC controller power return. Connected to the drain of the
internal pass−switch
Open Drain Power Good Indicator. Pin is in HZ mode when the
power good signal is active.
No connection
Under−voltage lockout input. Voltage with respect to VPORTN.
Connect a resistor−divider from VPORTP to UVLO to
VPORTNx to set an external UVLO threshold.
Auxiliary Pin. When this pin is pulled up, the Pass Switch is
disabled and allows a supply transition from PSE to the rear
auxiliary supply connected between VPORTP and RTN.
Positive input power. Voltage with respect to VPORTN.
