Product details

Dual-slot PCMCIA power switch — 70 mOhm, 1 A, three-rail support

The Texas Instruments TPS2211APWP is a dual-output high-side power switch designed for PCMCIA and CardBus slots. It integrates two 70 mOhm typical Rds(on) switches that deliver up to 1 A each, with support for 3.3 V, 5 V, and 12 V load rails — covering Vcc and Vpp programming voltages in a single IC. The 3:2 input-to-output ratio allows three control signals to manage two slot outputs, simplifying the host interface. A parallel control interface and a Status Flag output provide slot-power status feedback to the system controller.

70 mOhm Rds(on) and thermal design in HTSSOP

Without it, junction temperature rises quickly under continuous 1 A on both channels. No external Vcc supply is required — the switch is self-powered from the load rails.

Fault protection and 12 V programming support

Fixed current limiting and over-temperature shutdown protect the switch and the card slot against shorts or overcurrent events. The 12 V rail support is essential for programming PCMCIA flash memory cards that require Vpp at 12 V.

Frequently asked questions

Is the TPS2211APWP obsolete?

No. The product status is listed as active.

What is the difference between TPS2211APWP and TPS2211AIDWP?

The suffix indicates package variation: the APWP uses the 20-PowerTSSOP (HTSSOP) with a 4.40 mm body width, while the AIDWP uses a different package variant. Functionally both are the same dual PCMCIA switch with identical ratings.
