PCMCIA power switch — 4 outputs, 1 A each, 60 mOhm
The Texas Instruments TPS2216DBRG4 is a 4-output high-side PCMCIA switch designed to distribute power to PCMCIA/CardBus slots. It handles load voltages of 3.3 V, 5 V, and 12 V, delivering up to 1 A per output with a typical on-resistance of 60 mOhm. Control is via a serial interface, and the switch includes a status flag output for fault reporting. Built-in protection covers current limiting (fixed) and over-temperature shutdown.
30-SSOP footprint and industrial temperature grade
The 1:1 input-to-output ratio means each of the four outputs is independently controlled. No external Vcc supply is required for the switch logic — the part is self-powered from the load rail.
