TPS2375PW-1

Texas Instruments · Power Over Ethernet (PoE) Controllers · TSSOP-8

TPS2375PW-1 from Texas Instruments, in a TSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ILIM output Inrush current limit programming output; connect external resistor from this pin to VSS with value range 62.5 kΩ to 500 kΩ to set start-up inrush current limit according to I(LIM) = 25000/R(ILIM) in amperes.
2 CLASS output Classification programming output; connect external resistor from this pin to VSS to set IEEE 802.3af power class with values ranging from 255 Ω to 4420 Ω per Table 1.
3 DET output Detection output; connect 24.9-kΩ ±1% detection resistor from this pin to VDD for valid powered device detection when input voltage is between 1.4 V and 11.3 V.
4 VSS power_in Ground return line on source side of TPS2375-1; serves as local ground and voltage reference for the PSE input.
5 RTN power_out Switched output return line serving as low-side reference for downstream load circuits; carries operational and inrush current limit control current with maximum sinking capability of 515 mA.
6 PG tri_state Open-drain power-good output active high; goes to high resistance state when internal MOSFET is enabled and not in inrush current limiting mode, otherwise pulled to RTN; requires pullup resistor or interface.
7 NC unconnected No connection; unused pin.
8 VDD power_in Positive supply input from rectified PSE with absolute maximum voltage of 100 V; provides operating power and enables voltage monitoring for mode detection across 0 V to 57 V recommended operating range.
