LM5109AMAX-JSM from JSMSEMI, in a SOP-8. 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 | VCC | power_in | Low-side supply voltage; recommended 6 V to 20 V, absolute maximum 25 V. |
| 2 | HIN | input | High-side logic signal input; recommended 0 V to VCC, compatible with 3.3 V, 5 V and 15 V logic. |
| 3 | LIN | input | Low-side logic signal input; recommended 0 V to VCC, compatible with 3.3 V, 5 V and 15 V logic. |
| 4 | VSS | power_in | Ground reference for the device; all voltage ratings are referenced to VSS. |
| 5 | LO | output | Low-side gate drive output; 0 V to VCC, 1.2 A source / 1.5 A sink capability. |
| 6 | VS | power_in | High-side floating ground (return); recommended -9 V to 250 V. |
| 7 | HO | output | High-side gate drive output; recommended VS to VB. |
| 8 | VB | power_in | High-side floating supply; recommended VS+6 V to VS+20 V, absolute maximum 275 V. |
