# EG44273

**EG Micro** · Gate Drivers · SOT-23-5

EG44273 from EG Micro, 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 (named IN+ in the pin table); the output goes low when this pin is left floating, with logic-high threshold 2.5 V min and logic-low threshold 1.0 V max, and input voltage limited to 0 to VCC. |
| 2 | GND | power_in | Chip ground terminal. |
| 3 | OUT | output | Gate driver output rated for 2 A peak source (VO=0 V, PW≤10 µS) and 2 A peak sink, with absolute maximum OUT voltage of -0.3 V to VCC+0.3 V. |
| 4 | OUT | output | Gate driver output, listed in the pin table as a second OUT pin; the datasheet gives the same drive ratings and voltage limits as pin 3. |
| 5 | VCC | power_in | Supply pin with operating range 4 V to 20 V (12 V typical) and absolute maximum of 20 V. |
