STMicroelectronics · Power Distribution Switches · SOT-23-5
STMPS2171STR from STMicroelectronics, in a SOT-23-5. 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 | OUT | output | Switched power output from the high-side MOSFET, rated to supply 1000 mA continuous current with 90 mΩ typical on-resistance. |
| 2 | GND | power_in | Ground reference. |
| 3 | FAULT | tri_state | Open drain fault indicator output, active low after fault blanking when thermal shutdown, UVLO, or overcurrent condition occurs. |
| 4 | EN | input | Active high enable input for the power switch, accepts CMOS and TTL compatible logic levels. |
| 5 | IN | power_in | Power supply input, 2.7 to 5.5 V recommended operating range. |
