TEXAS INSTRUMENTS TPS2220A TPS2223A TPS2224A TPS2226A handbook
The document details the Texas Instruments TPS222x family of CardBus power-interface switches designed for serial PCMCIA controllers. These devices provide an integrated solution for distributing 3.3 V, 5 V, and 12 V to single or dual card slots while eliminating the need for external fuses through built-in current-limiting and thermal-protection features.
The datasheet specifies electrical characteristics, absolute maximum ratings, recommended operating conditions, and logic section parameters. It covers various package options including DB-24, DB-30, and HTSSOP (PowerPAD), along with ordering information for lead-free and green compliant devices.
