Pin Functions

PIN I/O DESCRIPTION
NAME NO.
'76-H
CLASS 2 O Connect a resistor from CLASS to VSS to set the classification of the powered device (PD). The IEEE classification levels and corresponding resistor values are shown in Table 1.
DET 3 O Connect a 24.9-kΩ detection resistor from DET to VDD.
ILIM 1 O Connect a resistor from ILIM to VSS to set the start-up inrush current limit. The equation for calculating the resistor is shown in the detailed pin description section for ILIM.
PG 6 O Open-drain, power-good output, active high, referenced to RTN.
RTN 5 O Switched output side return line used as the low-side reference for the TPS2376-H load.
UVLO 7 I UVLO comparator input that controls pass-device turn-on and off. Connect UVLO to a resistor divider from VDD to VSS.
VDD 8 I Positive line from the rectified PSE provided input.
VSS 4 I Return line on the source side of the TPS2376-H from the PSE.
PowerPad™ — I The PowerPad must be connected to VSS. The VSS copper on the circuit board must be a large fill area to assist in heat dissipation.
