TPS2412D 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; VDD must be connected to a supply voltage of 3 V or greater. |
| 2 | RSET | input | Connect a resistor from this pin to GND to program the fast turnoff threshold; leaving RSET open gives a slightly positive V(A-C) turnoff threshold. |
| 3 | RSVD | power_in | Reserved pin that must be connected to GND. |
| 4 | GND | power_in | Device ground and input supply reference, which should have a low-impedance connection to the ground plane. |
| 5 | GATE | output | Drives the gate of the external N-channel MOSFET to emulate a low forward-voltage diode; connect with low impedance to maximize turnoff current. |
| 6 | C | input | Voltage sense input for the simulated diode cathode; connect to the MOSFET drain in the typical configuration. |
| 7 | A | input | Voltage sense input for the simulated diode anode and reference for the charge-pump bias on BYP; connect to the MOSFET source in the typical configuration. |
| 8 | BYP | bidirectional | Charge-pump output and gate-drive supply; connect a storage capacitor from BYP to A to filter the gate drive supply voltage. |
