IRS4427S-MNS from Minos, in a SOIC-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 | NC | unconnected | Marked as an empty (no-connect) pin in the pin function table; leave it unconnected. |
| 2 | INA | input | Channel A logic input with VIH min 2.4 V and VIL max 0.8 V, rated from GND-10 V to VCC+0.3 V; it has an internal pull-down to GND, so tie it to GND if unused. |
| 3 | GND | power_in | Ground pin; all voltage ratings are referenced to GND, and the datasheet recommends a single-point star ground connected to the power MOSFET source. |
| 4 | INB | input | Channel B logic input with VIH min 2.4 V and VIL max 0.8 V, rated from GND-10 V to VCC+0.3 V; it has an internal pull-down to GND, so tie it to GND if unused. |
| 5 | OUTB | output | Channel B non-inverting gate-drive output that sources or sinks up to 2 A peak. |
| 6 | VCC | power_in | Supply pin with recommended operating range 4.5 V to 20 V and absolute maximum 25 V, requiring low-ESR/ESL bypass capacitors placed close to VCC and GND. |
| 7 | OUTA | output | Channel A non-inverting gate-drive output that sources or sinks up to 2 A peak. |
| 8 | NC | unconnected | Marked as an empty (no-connect) pin in the pin function table; leave it unconnected. |
