# IRS2304STR

**UMW** · Gate Drivers · SOP-8

IRS2304STR 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 | LIN | input | Logic input for the low-side gate driver output (LO), in phase; logic input levels are 0 to VCC, with VIH at least 2.5 V and VIL at most 0.8 V. |
| 2 | HIN | input | Logic input for the high-side gate driver output (HO), in phase; logic input levels are 0 to VCC, with VIH at least 2.5 V and VIL at most 0.8 V. |
| 3 | VCC | power_in | Low-side and logic fixed supply, recommended 10 V to 20 V, absolute maximum -0.3 V to 25 V. |
| 4 | COM | power_in | Low-side return; all voltage parameters are referenced to COM. |
| 5 | LO | output | Low-side gate drive output, swinging between 0 and VCC. |
| 6 | VS | power_in | High-side floating supply return, recommended -9 V to 700 V, and VB must be kept 10 V to 20 V above VS. |
| 7 | HO | output | High-side gate drive output, swinging between VS and VB. |
| 8 | VB | power_in | High-side floating supply, recommended VS + 10 V to VS + 20 V, absolute maximum -0.3 V to 725 V. |
