EG4427 from EG Micro, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connection. |
| 2 | INA | input | Logic input control signal for output OUTA; high level (≥2.5V) produces high output, low level produces low output. |
| 3 | GND | power_in | Chip ground reference. |
| 4 | INB | input | Logic input control signal for output OUTB; high level (≥2.5V) produces high output, low level produces low output. |
| 5 | OUTB | output | Path B output with 1.5A push-pull drive capability; logic state determined by INB input unless SD is high. |
| 6 | VDD | power_in | Chip power supply; voltage range 3V to 20V. |
| 7 | OUTA | output | Path A output with 1.5A push-pull drive capability; logic state determined by INA input unless SD is high. |
| 8 | SD | input | Active-high shutdown input; when high, forces both OUTA and OUTB outputs to low level regardless of INA and INB states. |
