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

LM5106MMX 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, decoupled to VSS with low ESR/ESL capacitor. |
| 2 | HB | power_in | High-side bootstrap supply, voltage range HS + 8 to HS + 14 V. |
| 3 | HO | output | High-side gate driver output, voltage range HS - 0.3 to HB + 0.3 V, drives high-side N-MOS gate. |
| 4 | HS | input | High-side MOSFET source, voltage range -1 to 100 V relative to VSS. |
| 5 | NC | unconnected | Not connected. |
| 6 | RDT | input | Dead-time programming input, resistor to VSS programs turnon delay, voltage range -0.3 to 5 V. |
| 7 | EN | input | Logic input for driver enable/disable, TTL compatible with hysteresis, disables LO and HO when low. |
| 8 | IN | input | Logic input for gate driver control, TTL compatible with hysteresis, high turns on high-side and off low-side. |
| 9 | VSS | power_in | Ground return, all signals referenced to VSS. |
| 10 | LO | output | Low-side gate driver output, voltage range -0.3 to VDD + 0.3 V, drives low-side N-MOS gate. |
