# JSM2101STR

**JSMSEMI** · Gate Drivers · SOP-8

JSM2101STR 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 and logic fixed supply; recommended 10V to 20V, absolute maximum 25V. |
| 2 | HIN | input | Logic input for high side gate driver output (HO), in phase; 0 to VCC. |
| 3 | LIN | input | Logic input for low side gate driver output (LO), in phase; 0 to VCC. |
| 4 | VSS | power_in | Low side return (ground reference for logic and low side supply). |
| 5 | LO | output | Low side gate drive output, swings 0 to VCC. |
| 6 | VS | power_in | High side floating supply return; recommended -9V to 700V. |
| 7 | HO | output | High side gate drive output, swings VS to VB. |
| 8 | VB | power_in | High side floating supply; VS+10V to VS+20V recommended, absolute maximum 725V. |
