# TPS2412PWR

**Texas Instruments** · Power Distribution Switches · TSSOP-8

TPS2412PWR 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 | VDD | power_in | Input power for the gate drive charge pump and internal controls; must be connected to a supply voltage ≥ 3 V. |
| 2 | RSET | input | Resistor connection to ground programs the turnoff threshold; open circuit results in slightly positive V(A-C) turnoff threshold. |
| 3 | RSVD | power_in | Reserved pin; must be connected to GND. |
| 4 | GND | power_in | Device ground. |
| 5 | GATE | output | Gate drive output to control external MOSFET and emulate a low forward-voltage diode. |
| 6 | C | input | Voltage sense input that connects to the simulated diode cathode; typically connected to MOSFET drain. |
| 7 | A | input | Voltage sense input that connects to the simulated diode anode; serves as reference for the charge-pump bias supply on BYP; typically connected to MOSFET source. |
| 8 | BYP | bidirectional | Internal charge pump output that supplies internal circuits and GATE driver; connect storage capacitor from BYP to A to filter the gate drive supply voltage. |

## CAD (KiCad official)

- Symbol: `TPS2412PWR`
- Footprint: `Package_SO:TSSOP-8_3x3mm_P0.65mm`
- 3D model: TSSOP-8 (KiCad packages3D, STEP)
- 3D model files: `tps2412pwr-etched.step` / `tps2412pwr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps2412pwr.step` / `tps2412pwr.glb` are the bare package body.
