LM5102MMX 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 voltage; operating range 9V to 14V, must be decoupled to VSS using low ESR/ESL capacitor placed close to IC. |
| 2 | HB | power_in | High-side gate driver bootstrap rail; connect positive terminal of bootstrap capacitor here with voltage range VHS + 8V to VHS + 14V. |
| 3 | HO | output | High-side gate driver output; drives high-side MOSFET gate with 15-ns rise and fall time on 1000-pF loads, 25-ns maximum turn-off propagation delay. |
| 4 | HS | power_in | High-side MOSFET source connection; floating reference node for high-side driver with operating range -1V to 100V relative to VSS. |
| 5 | RT1 | passive | High-side rising edge delay programming resistor; resistor from RT1 to ground programs the leading edge delay of high-side gate driver output. |
| 6 | RT2 | passive | Low-side rising edge delay programming resistor; resistor from RT2 to ground programs the leading edge delay of low-side gate driver output. |
| 7 | HI | input | High-side driver control input with TTL-compatible thresholds; unused inputs must be tied to ground and not left open. |
| 8 | LI | input | Low-side driver control input with TTL-compatible thresholds; unused inputs must be tied to ground and not left open. |
| 9 | VSS | power_in | Ground return; all signals are referenced to this ground connection. |
| 10 | LO | output | Low-side gate driver output; drives low-side MOSFET gate with 15-ns rise and fall time on 1000-pF loads, 25-ns maximum turn-off propagation delay. |
