4409A from HL, in a SOP-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 | S | passive | Source terminal of the P-channel MOSFET; the datasheet gives a continuous source current limit of -14 A at TA=25°C for the body diode (IS). |
| 2 | S | passive | Source terminal of the P-channel MOSFET; the datasheet gives a continuous source current limit of -14 A at TA=25°C for the body diode (IS). |
| 3 | S | passive | Source terminal of the P-channel MOSFET; the datasheet gives a continuous source current limit of -14 A at TA=25°C for the body diode (IS). |
| 4 | G | input | Gate terminal of the P-channel MOSFET; the gate-source voltage is rated at ±20 V (VGS) in the absolute maximum ratings. |
| 5 | D | passive | Drain terminal of the P-channel MOSFET; drain-source voltage is rated at -30 V (VDS) with continuous drain current of -18 A at Ta=25°C. |
| 6 | D | passive | Drain terminal of the P-channel MOSFET; drain-source voltage is rated at -30 V (VDS) with continuous drain current of -18 A at Ta=25°C. |
| 7 | D | passive | Drain terminal of the P-channel MOSFET; drain-source voltage is rated at -30 V (VDS) with continuous drain current of -18 A at Ta=25°C. |
| 8 | D | passive | Drain terminal of the P-channel MOSFET; drain-source voltage is rated at -30 V (VDS) with continuous drain current of -18 A at Ta=25°C. |
