STMPS2141TTR

Controlled by logical levels power switch with adjustable current limit and protection against too low / too high voltage, excessive current or overheating. Power supply from 3 V - 5.5 V, housing WLCSP-9. NX5P2190UKZ

Analog switch in double DPDT configuration, operating at 1.65 - 4.45 V, with very low resistance of just 2 Ω.

The STMPS2141STR system is a power switch designed for circuits with high capacitive loads and short circuits. The system is equipped with an N-channel MOSFET 90 mΩ controlled by the input logic level.
