The Texas Instruments TPS2206ADAPR is a four-output high-side PCMCIA power switch array, designed to distribute 3.3 V, 5 V, and 12 V rails to two PCMCIA card slots with a 3:4 input-to-output ratio. Each output is rated for 1 A continuous with a typical Rds(on) of 95 mOhm, and the switch integrates current limiting and over-temperature fault protection. The serial interface and status flag output allow a host controller to monitor and control each slot's power state.
Key ratings that drive fit
The 1 A per-output ceiling sets the load budget for each PCMCIA slot. The 3:4 input-to-output ratio means three supply inputs are switched to four outputs. The serial interface controls slot power sequencing, and the status flag reports fault conditions.
