TPS2376PWR
Texas Instruments · Power Over Ethernet (PoE) Controllers · TSSOP-8
TPS2376PWR 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 | passive | A resistor from ILIM to VSS sets the inrush current limit per I(LIM) = 25000 / R(ILIM), with R(ILIM) practically limited to 62.5 kΩ to 500 kΩ (178 kΩ recommended for legacy PSEs), and the pin must not be left open or shorted to VSS. |
| 2 | CLASS | passive | An external resistor R(CLASS) from CLASS to VSS sets the PD power classification, with the controller drawing classification current when V(VDD) is between 13 V and 21 V, and the pin must not be shorted to ground. |
| 3 | DET | passive | A 24.9 kΩ ±1% detection resistor connects from DET to VDD, is placed across the input line when V(VDD) is between 1.4 V and 11.3 V, and is disconnected above that range. |
| 4 | VSS | power_in | Input supply negative rail that serves as the local ground and return line from the PSE for the device. |
| 5 | RTN | power_out | Switched negative power rail used as the low-side reference for downstream circuits, with a specified sinking operating current range of 0 to 350 mA and a V(RTN) rating of 0 to 57 V. |
| 6 | PG | output | Open-drain, active-high power-good output that is pulled to RTN in all states except detection and requires at least 4 V between VDD and RTN, with a sinking current of 0 to 2 mA recommended. |
| 7 | UVLO | input | TPS2376-only pin used with an external resistor divider from VDD to VSS to set the adjustable upper and lower UVLO thresholds, with a recommended input voltage range of 0 to 5 V. |
| 8 | VDD | power_in | Positive input supply from the rectified PSE input, with a recommended input voltage range of 0 to 57 V and an absolute maximum of 100 V. |
