**JSMSEMI** · Gate Drivers · SOP-14

IR21814STRPBF-JSM from JSMSEMI, in a SOP-14. 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 | HIN | input | High-side logic signal input, compatible with 3.3V, 5V and 15V logic, with VIN range 0 to VCC. |
| 2 | LIN | input | Low-side logic signal input, compatible with 3.3V, 5V and 15V logic, with VIN range 0 to VCC. |
| 3 | VSS | power_in | Digital (logic) ground, the reference for all voltage ratings. |
| 4 | NC | unconnected | No connection (empty pin). |
| 5 | COM | power_in | Power ground, the low-side return for the LO output. |
| 6 | LO | output | Low-side gate driver output with 4.0A source/4.0A sink capability, range 0 to VCC. |
| 7 | VCC | power_in | Low-side supply voltage, recommended 10V to 20V (absolute max 25V). |
| 8 | NC | unconnected | No connection (empty pin). |
| 9 | NC | unconnected | No connection (empty pin). |
| 10 | NC | unconnected | No connection (empty pin). |
| 11 | VS | power_in | High-side floating ground, recommended -9V to 700V. |
| 12 | HO | output | High-side gate driver output with 4.0A source/4.0A sink capability, swinging between VS and VB. |
| 13 | VB | power_in | High-side floating supply, recommended VS+10V to VS+20V (absolute max 725V). |
| 14 | NC | unconnected | No connection (empty pin). |
