# TPS2412DR

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

TPS2412DR from Texas Instruments, in a SOIC-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 | Connect a resistor to ground to program the fast turnoff threshold; leaving RSET open results in a slightly positive V(A-C) turnoff threshold. |
| 3 | RSVD | power_in | Reserved pin; must be connected to GND. |
| 4 | GND | power_in | Device ground; reference for all voltage measurements. |
| 5 | GATE | output | Output to external N-channel MOSFET gate; controls the MOSFET to emulate a low forward-voltage diode. |
| 6 | C | input | Voltage sense input for simulated diode cathode; connect to MOSFET drain in typical configuration. |
| 7 | A | input | Voltage sense input for simulated diode anode and reference for charge-pump bias supply; connect to MOSFET source in typical configuration. |
| 8 | BYP | bidirectional | Charge pump output and positive supply for internal comparators and gate driver; connect a storage capacitor from BYP to A to filter the gate drive supply voltage. |

## CAD (KiCad official)

- Symbol: `TPS2412DR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `tps2412dr-etched.step` / `tps2412dr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps2412dr.step` / `tps2412dr.glb` are the bare package body.
