# LM5114BMF

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

LM5114BMF 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 voltage with recommended operating range of 4-V to 12.6-V; locally decouple to VSS using low ESR/ESL capacitor placed as close as possible to the IC. |
| 2 | P_OUT | output | Source-current open-drain pullup output with 2-Ω on-resistance providing 1.3-A peak drive current; connect to MOSFET gate with short, low inductance path to adjust turnon speed. |
| 3 | N_OUT | output | Sink-current open-drain pulldown output with 0.23-Ω on-resistance providing 7.6-A peak drive current; connect to MOSFET gate with short, low inductance path to adjust turnoff speed. |
| 4 | VSS | power_in | Ground reference; all signals are referenced to this ground; recommended to solder exposed pad on bottom to ground plane to aid thermal dissipation. |
| 5 | INB | input | Inverting TTL/CMOS logic input with 0.68-V input hysteresis; accepts up to 14-V input voltage regardless of VDD level; connect to VSS when not used. |
| 6 | IN | input | Noninverting TTL/CMOS logic input with 0.68-V input hysteresis; accepts up to 14-V input voltage regardless of VDD level; connect to VDD when not used. |
