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.
