STMPS2151TTR from STMicroelectronics, in a MSOP-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 | Power switch input, specified for 2.7 to 5.5 V. |
| 3 | IN | power_in | Second power switch input pin, specified for 2.7 to 5.5 V. |
| 4 | EN | input | Enable input for the power switch; CMOS and TTL compatible, and active high for the STMPS2151 per Table 1. |
| 5 | FAULT | output | Open-drain FAULT indicator, active low; asserts low after a 10 ms blanking period for current-limit faults, and immediately for overtemperature or undervoltage faults. |
| 6 | OUT | power_out | Output of the power switch, rated for 500 mA continuous output current for the STMPS2151. |
| 7 | OUT | power_out | Output of the power switch, rated for 500 mA continuous output current for the STMPS2151. |
| 8 | OUT | power_out | Output of the power switch, rated for 500 mA continuous output current for the STMPS2151. |
