# IRS2003STR

**UMW** · Gate Drivers · SOP-8

IRS2003STR from UMW, 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 operating range 10 V to 20 V referenced to VSS. |
| 2 | HIN | input | Logic input for the high side gate driver output (HO), in phase; accepts 3.3 V, 5 V and 15 V logic, with recommended range 0 to VCC. |
| 3 | LIN | input | Logic input for the low side gate driver output (LO), out of phase; accepts 3.3 V, 5 V and 15 V logic, with recommended range 0 to VCC. |
| 4 | VSS | power_in | Low side return, the reference for all voltage parameters, rated at 0 V in the recommended operating conditions. |
| 5 | LO | output | Low side gate drive output, with a recommended range of 0 V to VCC. |
| 6 | VS | power_in | High side floating supply return, with a recommended range of -9 V to 250 V and an allowable negative transient of -9 V. |
| 7 | HO | output | High side gate drive output, with a recommended range of VS to VB. |
| 8 | VB | power_in | High side floating supply, with a recommended range of VS + 10 V to VS + 20 V. |

## CAD (KiCad official)

- Symbol: `IRS2003STR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `irs2003str-etched.step` / `irs2003str-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `irs2003str.step` / `irs2003str.glb` are the bare package body.
