FUNCTION
Positive Supply Input. Connect a 68nF (min) bypass capacitor between V DD and V SS .
Detection Resistor Input. Connect a signature resistor (R DET = 24.9k I ) from DET to V DD .
No Connection. Not internally connected.
Internally Connected. Leave unconnected.
Negative Supply Input. V SS connects to the source of the integrated isolation n-channel power
MOSFET.
Drain of Isolation MOSFET. RTN connects to the drain of the integrated isolation n-channel power
MOSFET. Connect RTN to the downstream DC-DC converter ground as shown in the Typical
Application Circuit .
Wall Power Adapter Detector Input. Wall adapter detection is enabled the moment V DD - V SS crosses
the mark event threshold. Detection occurs when the voltage from WAD to RTN is greater than 9V.
When a wall power adapter is present, the isolation n-channel power MOSFET turns off, 2EC current
sink turns on. Connect WAD directly to RTN when the wall power adapter or other auxiliary power
source is not used.
Open-Drain Power-Good Indicator Output. PG sinks 230 F A to disable the downstream DC-DC converter
while turning on the hot-swap MOSFET switch until the hot-swap switch is fully on. PG current sink is
disabled during detection, classification, and in the steady-state power mode.
Active-Low 2-Event Classification Detect or Wall Adapter Detect Output. A 1.5mA current sink is
enabled at 2EC when a Type 2 PSE or a wall adapter is detected. When powered by a Type 2 PSE, the
2EC current sink is enabled and latched low after the isolation MOSFET is fully on until V IN drops below
the UVLO threshold. 2EC also asserts when a wall adapter supply, typically greater than 9V, is applied
between WAD and RTN. 2EC is not latched if asserted by WAD.
Classification Resistor Input. Connect a resistor (R CLS ) from CLS to V SS to set the desired classification
current. See the classification current specifications in the Electrical Characteristics table to find the resis-
tor value for a particular PD classification.
Exposed Pad. Do not use EP as an electrical connection to V SS . EP is internally connected to V SS
through a resistive path and must be connected to V SS externally. To optimize power dissipation, solder
the exposed pad to a large copper power plane.
