IRS44273LTRPBF from Infineon Technologies, in a SOT-23-5. 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 | IN | input | Logic input for the gate driver output OUT; VIH is at least 2.5 V and VIL is at most 0.8 V, with VIN rated from 0 to VCC. |
| 2 | COM | power_in | Ground reference; all voltage parameters in the datasheet are absolute voltages referenced to COM. |
| 3 | OUT | output | Gate drive output with a current buffer stage, rated for VO from 0 to VCC and 1.5 A typical peak source/sink (IO+ and IO-). |
| 4 | OUT | output | Gate drive output, electrically tied to pin 3 as a second OUT lead; VO is rated from 0 to VCC. |
| 5 | VCC | power_in | Fixed supply voltage, recommended 10 V to 20 V (absolute maximum 25 V relative to COM), with undervoltage lockout around 10.2 V typical on the positive-going threshold. |
