DT
Delay time set.
A resistor connected from this pin to ARTN sets the delay time between GAT1 and
GAT2. This pin cannot be left open.
21
FRS
Switching frequency set.
An external resistor connected from FRS to ARTN sets the oscillator frequency.
22
T2P
Successful 2-event classification indicator.
T2P open-drain signal assertion happens when powered by a PSE performing a 2-
event classification. T2P is an active-low signal.
23
LED
Sleep mode LED indicator.
An LED connected to VSS is driven by a 250 Hz, 12 mA PWM current. The LED
brightness can be set through the DIM pin.
24
WKUP
Wake-up signal.
Closing the switch from WKUP to VSS, the PM8801 wakes up from sleep mode,
enabling the DC/DC controller with a soft-start. The WKUP is an active-low input.
EP
Exposed Pad.
Connect this pad to a pcb copper plane to improve heat dissipation; must be
electrically connected to VSS.
