STMPS2171TTR

STMicroelectronics · Power Distribution Switches · MSOP-8

STMPS2171TTR 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 device.
2 IN power_in Power switch input supply, specified for 2.7 to 5.5 V input.
3 IN power_in Power switch input supply, specified for 2.7 to 5.5 V input.
4 EN input Enable input for the power switch; the STMPS2171 is active high per Table 1.
5 FAULT output Open drain FAULT indicator, active low, asserted after a blanking period for current limit faults or immediately for overtemperature and undervoltage.
6 OUT power_out Output of the power switch.
7 OUT power_out Output of the power switch.
8 OUT power_out Output of the power switch.
