STG3682QTR from STMicroelectronics, in a QFN-10(1.8x1.4). 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 | 1S1 | bidirectional | Independent switch terminal of pair 1; connects to common D1 when SEL1 is high via ON-resistance of 4.6Ω at VCC=4.3V. |
| 2 | D1 | bidirectional | Common terminal for switch pair 1; routes to 1S1 when SEL1 is high or to 1S2 when SEL1 is low. |
| 3 | 1S2 | bidirectional | Independent switch terminal of pair 1; connects to common D1 when SEL1 is low via ON-resistance of 4.6Ω at VCC=4.3V. |
| 4 | SEL2 | input | Digital control input for switch pair 2; high selects 2S1 (S1 ON), low selects 2S2 (S2 ON). |
| 5 | GND | power_in | Ground (0V) reference. |
| 6 | 2S1 | bidirectional | Independent switch terminal of pair 2; connects to common D2 when SEL2 is high via ON-resistance of 4.6Ω at VCC=4.3V. |
| 7 | D2 | bidirectional | Common terminal for switch pair 2; routes to 2S1 when SEL2 is high or to 2S2 when SEL2 is low. |
| 8 | 2S2 | bidirectional | Independent switch terminal of pair 2; connects to common D2 when SEL2 is low via ON-resistance of 4.6Ω at VCC=4.3V. |
| 9 | VCC | power_in | Positive supply voltage; operating range 1.65V to 4.3V single supply. |
| 10 | SEL1 | input | Digital control input for switch pair 1; high selects 1S1 (S1 ON), low selects 1S2 (S2 ON). |
