# LM5134BMFX

**Texas Instruments** · Gate Drivers · SOT-23-6

LM5134BMFX from Texas Instruments, in a SOT-23-6. 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 | Gate drive supply; locally decouple to VSS with a low ESR/ESL capacitor placed as close as possible to the IC. |
| 2 | PILOT | output | Gate drive output for an external turnoff FET; connect to the gate of a small turnoff MOSFET with a short, low-inductance path so it provides a local turnoff path. |
| 3 | OUT | output | Gate drive output for the power FET; connect to the power FET gate with a short, low-inductance path, and a gate resistor can be used to eliminate potential gate oscillations. |
| 4 | VSS | power_in | Ground reference; all signals are referenced to this pin. |
| 5 | INB | input | Inverting logic input; connect to VSS when not used. |
| 6 | IN | input | Non-inverting logic input; connect to VDD when not used. |
