Pin Description
Refer to Figure 1 for component reference designators CS for example ), and the Electrical Characteristics table
for values denoted by reference (VCSMAX for example). Electrical Characteristic values take precedence over any
numerical values used in the following sections.
APD
APD forces power to come from an external adapter connected from VDD1 to RTN by opening the hotswap
switch. A resistor divider is recommended on APD when it is connected to an external adapter. The divider
provides ESD protection, leakage discharge for the adapter ORing diode, and input voltage qualification. Voltage
qualification assures the adapter can support the PD before the PoE current is cut off.
Select the APD divider resistors per the following equations where VADPTR-ON is the desired adapter voltage that
enables the APD function as adapter voltage rises.
