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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-8 |+| Category | Power Management (PMIC) |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `TPS2376PWR`+- Footprint: `Package_SO:TSSOP-8_3x3mm_P0.65mm`+- 3D model: TSSOP-8 (KiCad packages3D, STEP)+- 3D model files: `tps2376pwr-etched.step` / `tps2376pwr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps2376pwr.step` / `tps2376pwr.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tps2376.pdf) (28 pp, sha256 `6559d81e1161e551`, retrieved 2026-10-08, tier: manufacturer)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-5-5` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
