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

LM5102MM 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; decouple to VSS with low ESR/ESL capacitor placed as close to the IC as possible, with recommended VDD of 9 V to 14 V and absolute maximum of 18 V. |
| 2 | HB | power_in | High-side gate driver bootstrap rail; connect the positive terminal of the bootstrap capacitor here, with HB recommended at VHS + 8 V to VHS + 14 V and absolute maximum VHB to VHS of 18 V. |
| 3 | HO | output | High-side gate driver output, connected to the gate of the high-side MOSFET through a short, low-inductance path. |
| 4 | HS | power_in | High-side MOSFET source connection and bootstrap capacitor negative terminal; recommended HS range is -1 V to 100 V with slew rate below 50 V/ns. |
| 5 | RT1 | passive | Analog input for the high-side output rising edge delay; a resistor from RT1 to ground sets the delay, placed close to the IC, with RT1 to VSS absolute maximum of 5 V. |
| 6 | RT2 | passive | Analog input for the low-side output rising edge delay; a resistor from RT2 to ground sets the delay, placed close to the IC, with RT2 to VSS absolute maximum of 5 V. |
| 7 | HI | input | High-side driver TTL-compatible control input; unused inputs should be tied to ground and not left open, with absolute maximum range of -0.3 V to VDD + 0.3 V. |
| 8 | LI | input | Low-side driver TTL-compatible control input; unused inputs should be tied to ground and not left open, with absolute maximum range of -0.3 V to VDD + 0.3 V. |
| 9 | VSS | power_in | Ground return; all signals are referenced to this pin. |
| 10 | LO | output | Low-side gate driver output, connected to the gate of the low-side MOSFET through a short, low-inductance path, with absolute maximum range of -0.3 V to VDD + 0.3 V. |
