Product Summary

The TPS2202AIDBR is a PC Card power-interface switch provides an integrated power-management solution for two PC Cards. All of the discrete power MOSFETs, a logic section, current limiting, thermal protection, and power-good reporting for PC Card control are combined on a single integrated circuit (IC), using the Texas Instruments LinBiCMOS. process. The TPS2202AIDBR allows the distribution of 3.3-V, 5-V, and/or 12-V card power by means of the P2C (PCMCIA Peripheral-Control) Texas Instruments nonproprietary serial interface. The current-limiting feature eliminates the need for fuses, which reduces component count and improves reliability. Current-limit reporting can help the user isolate a system fault to a specific card.
