DESCRIPTION
The TPS2228 and TPS2221 PC card power interface
switches provide an integrated power management
solution for both dual and single PC card sockets. The
TPS2228 is a dual-slot power interface switch for serial
PCMCIA controllers. The TPS2221 is a single-slot power
interface switch for parallel PCMCIA controllers. These
power interface switches support the distribution of 3.3 V,
5 V and 1.8 V to the PC card slot while providing
current-limiting protection with overcurrent reporting.

(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
