IRS2181STR

UMW · Gate Drivers · SOP-8

IRS2181STR 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 HIN input Logic input for the high-side gate driver output HO, in phase; compatible with 3.3V, 5V and 15V input logic.
2 LIN input Logic input for the low-side gate driver output LO, in phase; compatible with 3.3V, 5V and 15V input logic.
3 COM power_in Low-side return (ground reference for the logic inputs and LO output); all voltage ratings are referenced to VSS.
4 LO output Low-side gate drive output; absolute maximum VLO is -0.3 V to VCC+0.3 V.
5 VCC power_in Low-side and logic fixed supply; recommended operating range is 10 V to 20 V.
6 VS power_in High-side floating supply return; recommended range is -9 V to 700 V, and absolute maximum is VB-25 V to 725 V.
7 HO output High-side gate drive output; absolute maximum VHO is VS-0.3 V to VB+0.3 V.
8 VB power_in High-side floating supply, referenced to VS; recommended range is VS+10 V to VS+20 V, and absolute maximum is 25 V above VS.
