STMPS2161MTR from STMicroelectronics, in a SO-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 | GND | power_in | Ground reference pin for the power switch. |
| 2 | IN | power_in | Input supply pin, specified for a 2.7 to 5.5 V input range. |
| 3 | IN | power_in | Second input supply pin on the SO-8 package, specified for the same 2.7 to 5.5 V input range as pin 2. |
| 4 | EN | input | Enable input for the power switch; it is active low for the STMPS2161 per Table 1 and is CMOS and TTL compatible. |
| 5 | FAULT | output | Open-drain FAULT indicator that goes active low on overcurrent after the 10 ms fault blanking time, and immediately on overtemperature (above 135 °C junction) or undervoltage. |
| 6 | OUT | power_out | Output of the 90 mΩ high-side power switch, rated for 1000 mA continuous output current on the STMPS2161. |
| 7 | OUT | power_out | Output of the 90 mΩ high-side power switch, rated for 1000 mA continuous output current on the STMPS2161. |
| 8 | OUT | power_out | Output of the 90 mΩ high-side power switch, rated for 1000 mA continuous output current on the STMPS2161. |
