FDC6331L

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.

Enhanced dual channel power switches are intended for applications where heavy capacitive loads and short-circuits are likely to be encountered. Use for power distribution systems that require multiple power switches in a single package. STMicroelectronics STMPS2252TTR

Dual-Channel Power Distribution Switch, SOIC8, Micrel Inc, RoHS

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

The LT4276 is a pin-for-pin compatible family of IEEE 802.3 and LTPoE++ Powered Device (PD) controllers. It includes an isolated switching regulator controller capable of synchronous operation in both forward and flyback topologies with auxiliary power support.
