CMS4443A from Cmos, 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, rated for the device's VDS of -40 V and continuous ID of -6 A. |
| 2 | S | passive | Source terminal of the P-channel MOSFET, rated for the device's VDS of -40 V and continuous ID of -6 A. |
| 3 | S | passive | Source terminal of the P-channel MOSFET, rated for the device's VDS of -40 V and continuous ID of -6 A. |
| 4 | G | input | Gate terminal, with VGS limited to ±20 V per the absolute maximum ratings and a gate threshold of -1 V to -3 V. |
