NX5P2190UKZ - power switch with current limitation and protection

Integrated Load Switch, SSOT6, Fairchild Semiconductor, RoHS

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.

TPS2024D is an integrated circuit from Texas Instruments, functioning as a power-distribution switch with a single output channel. It is designed to operate as a high-side switch with a built-in N-Channel MOSFET, allowing control of loads up to 2 A.

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

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

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

Analog Switch ICs 5-V, 2:1 (SPDT), 2-channel analog switch with powered-off protection 10-VSSOP -40 to 125°C, , VSSOP-10

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.
