**Texas Instruments** · Gate Drivers · VSSOP-10-0.5mm

LM5106MM from Texas Instruments, in a VSSOP-10-0.5mm. 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 | Positive gate drive supply with recommended operating voltage 8-14 V; decouple to VSS using a low ESR/ESL capacitor placed as close to the IC as possible. |
| 2 | HB | power_in | Bootstrap supply positive rail; connect positive terminal of bootstrap capacitor here with voltage relative to HS of 8-14 V. |
| 3 | HO | output | High-side gate driver output; connect to the gate of the high-side N-MOS device through a short, low inductance path. |
| 4 | HS | power_in | High-side MOSFET source node and bootstrap capacitor negative terminal connection; voltage floats from -1 to 100 V relative to VSS. |
| 5 | NC | unconnected | Not connected; no internal connection to the die. |
| 6 | RDT | input | Dead-time programming input; connect resistor from RDT to VSS to program the turnon delay of both MOSFETs with voltage range -0.3 to 5 V. |
| 7 | EN | input | TTL-compatible logic input for driver enable/disable with hysteresis; LO and HO held in low state when EN is low. |
| 8 | IN | input | TTL-compatible logic input for gate driver control with hysteresis; high-side MOSFET turned on and low-side turned off when IN is high. |
| 9 | VSS | power_in | Ground return; all signals are referenced to this ground. |
| 10 | LO | output | Low-side gate driver output; connect to the gate of the low-side N-MOS device through a short, low inductance path. |
