UMW · Gate Drivers · SOT-23-5
IRS44273LTR from UMW, 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 of the non-inverting gate driver, a CMOS Schmitt-trigger input compatible with CMOS or TTL logic levels down to 3.3 V. |
| 2 | COM | power_in | Ground reference pin; all signals are referenced to this pin. |
| 3 | OUT | output | Gate drive output with 2 A peak source and sink drive current; OUT voltage absolute range is -0.3 V to VCC+0.3 V relative to COM. |
| 4 | OUT | output | Gate drive output (second OUT pin) with 2 A peak source and sink drive current, sharing the same OUT rating as pin 3. |
| 5 | VCC | power_in | Bias supply input; the Features list gives a 5 V to 25 V single-supply range, while the Section 8 recommended maximum is 20 V. |
