STMPS2171MTR from STMicroelectronics, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Device ground return. |
| 2 | IN | power_in | Input supply to the high-side power switch, 2.7 V to 5.5 V. Tied together with pin 3 on the package (both are IN). |
| 3 | IN | power_in | Input supply to the high-side power switch, 2.7 V to 5.5 V. Tied together with pin 2 on the package (both are IN). |
| 4 | EN | input | Enable input for the power switch. CMOS/TTL compatible. Active-high on the STMPS2171 (switch is ON when EN is high). |
| 5 | FAULT | output | Open-drain FAULT indicator, active low. Asserts low after the 10 ms current-limit blanking period, or immediately on overtemperature or UVLO fault. Requires an external pull-up resistor. |
| 6 | OUT | power_out | Switched output of the high-side power switch, rated 1000 mA continuous. Pins 6, 7, and 8 are all OUT and are tied internally; connect all three to the load rail to share current. |
| 7 | OUT | power_out | Switched output of the high-side power switch. Pins 6, 7, and 8 are all OUT and are tied internally; connect all three to the load rail to share current. |
| 8 | OUT | power_out | Switched output of the high-side power switch. Pins 6, 7, and 8 are all OUT and are tied internally; connect all three to the load rail to share current. |
