The TPS2223A, TPS2224A, and TPS2226A CardBus™ power-interface switches provide an integrated power-management solution for two PC Card sockets. The TPS2220A is a single-slot option for this family of devices. These devices allow the controlled distribution of 3.3 V, 5 V, and 12 V to each card slot. The current-limiting and thermal-protection features eliminate the possibility of card failure due to overcurrent or overheating.
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.
