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 | SDA | bidirectional | Serial-bus data line, open-drain input/output; the absolute maximum voltage on SDA is -0.3 V to 6 V. |+| 2 | SCL | input | Serial-bus clock line, high-impedance input; SCL is limited to -0.3 V to (VS + 0.3) V. |+| 3 | ALERT | output | Open-drain multi-function serial-bus alert output, similar to the SMBus Alert function, with an absolute maximum voltage of 6 V. |+| 4 | VS | power_in | Monitor-section bias-supply input for POR1, control logic, ADC and serial bus, typically 2.7 V to 5.5 V. |+| 5 | N/C | unconnected | No connection; tie to GND or float. |+| 6 | EN | input | Hotswap-section enable input; the GATE driver is enabled when POR2 and UVLO are satisfied and the EN upper threshold is exceeded, with an absolute maximum of -0.3 V to 100 V. |+| 7 | VREF | power_in | Reference voltage output used to set the power-limit threshold on PROG; reference source current is recommended at 0 to 1 mA, with 2 mA absolute maximum. |+| 8 | PROG | input | Pass-MOSFET power-limit programming input, normally 0.4 V to 4 V from a resistor divider from VREF; voltages greater than 4 V must not be applied. |+| 9 | TIMER | input | Fault-timing capacitor connection to GND; TIMER latches off the TPS2482 at 4 V and must be tied to ground if the fault-timer feature is not used, and no external voltage may be applied. |+| 10 | GND | power_in | System ground; common reference for all other input and output voltages. |+| 11 | PG | output | Open-drain power-good output that goes high-impedance after pass-MOSFET VDS falls below 1.25 V and a 9-ms deglitch, and is held low when VDS is above 2.7 V or UVLO is active; absolute maximum output voltage is 100 V. |+| 12 | OUT | input | Input sensing pass-MOSFET source voltage for power-limit protection and PG state determination; if the load can drive OUT below ground, a clamp diode from OUT to GND is needed to keep VOUT above -0.3 V. |+| 13 | GATE | output | Pass-MOSFET gate-drive output with a 22 µA pull-up from the charge pump and a pull-down of at least 75 mA; absolute maximum output voltage is -0.3 V to 100 V. |+| 14 | SENSE | input | Input sensing pass-MOSFET drain voltage and the downstream side of the current-shunt RS; absolute maximum input voltage is -0.3 V to 100 V and it must not be driven to a large difference from VCC. |+| 15 | VCC | power_in | Hotswap-section bias-supply input and positive reference for shunt sensing; it must exceed the POR2 threshold (about 6 V) and UVLO turn-on (about 8.4 V), with a recommended range of 9 V to 80 V. |+| 16 | GND | power_in | System ground; common reference for all other input and output voltages. |+| 17 | VINM | input | Kelvin-connected negative (load) side of the current-sense resistor, also used to measure bus voltage to GND; monitor input range is 0 V to 36 V. |+| 18 | VINP | input | Kelvin-connected positive (source) side of the current-sense resistor; monitor sensing input range is 0 V to 36 V. |+| 19 | A1 | input | Serial-bus address input; connect to GND, SDA, SCL, or VS to select the slave address per Table 8. |+| 20 | A0 | input | Serial-bus address input; connect to GND, SDA, SCL, or VS to select the slave address per Table 8. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-20 |+| Category | Power Management (PMIC) |+| Pins | 20 |++## CAD (KiCad official)++- Symbol: `TPS2482PWR`+- Footprint: `Package_SO:TSSOP-20_4.4x6.5mm_P0.65mm`+- 3D model: TSSOP-20 (KiCad packages3D, STEP)+- 3D model files: `tps2482pwr-etched.step` / `tps2482pwr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps2482pwr.step` / `tps2482pwr.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/tps2482.pdf) (58 pp, sha256 `4af3cee11d85aa57`, 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.
