CSD85301Q2 from Texas Instruments, in a WSON-6(2x2). 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 | S1 | passive | Source of FET 1 (20V VDS rating, 5.0A package-limited continuous drain current). |
| 2 | G1 | input | Gate of FET 1, ±10V maximum VGS with 0.9V typical threshold and optimized for a 5V gate driver. |
| 3 | D2 | passive | Drain of FET 2, 20V maximum VDS, shared with the D2 center pad on the package bottom. |
| 4 | S2 | passive | Source of FET 2 (20V VDS rating, 5.0A package-limited continuous drain current). |
| 5 | G2 | input | Gate of FET 2, ±10V maximum VGS with 0.9V typical threshold and optimized for a 5V gate driver. |
| 6 | D1 | passive | Drain of FET 1, 20V maximum VDS, shared with the D1 center pad on the package bottom. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
