It integrates a 4:2 input-to-output multiplexer that selects among 3.3 V, 5 V, and 12 V load rails, routing the chosen voltage to two independent outputs, each rated for 1 A continuous. A serial interface controls the output configuration, and a status flag reports fault conditions back to the host controller — essential for hot-swap card insertion where the system must know when a slot is powered or faulted. ## Protection features and thermal limits Built-in fault protection includes fixed current limiting and over-temperature shutdown. The current limit is non-adjustable — set internally to protect the PCMCIA connector and card from sustained overcurrent events without external sense resistors. The 95 mOhm typical Rds(on) is specified for the 24-SSOP package. New production designs should select a current-generation PCMCIA or general-purpose power switch from the TI portfolio.","metaTitle":"TPS2220BDBR PCMCIA Power Switch, 95 mOhm, Obsolete","metaDescription":"Texas Instruments TPS2220BDBR PCMCIA switch, dual high-side output, 1 A, 95 mOhm, 3.3/5/12 V load.
