# SDH21263TR

**JSMSEMI** · Gate Drivers · SOP-8

SDH21263TR 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 max 25 V) with UVLO thresholds of 4.4 V rising and 4.2 V falling. |
| 2 | HIN | input | High-side logic input compatible with 3.3 V, 5 V and 15 V logic, with VIH min 2.5 V and VIL max 0.8 V. |
| 3 | LIN | input | Low-side logic input (active-low, shown with overbar), compatible with 3.3 V, 5 V and 15 V logic, with VIH min 2.5 V and VIL max 0.8 V. |
| 4 | VSS | power_in | Ground; logic and all voltage ratings are referenced to VSS. |
| 5 | LO | output | Low-side gate drive output swinging 0 V to VCC, with 1.2 A source and 1.5 A sink typical. |
| 6 | VS | power_in | High-side floating supply return (offset), operating range -9 V to 250 V. |
| 7 | HO | output | High-side gate drive output swinging from VS to VB, with 1.2 A source and 1.5 A sink typical. |
| 8 | VB | power_in | High-side floating supply, VS+5 V to VS+20 V recommended, absolute max 275 V. |
