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.
