资 源 简 介
The TPS2211A PC Card power-interface switch provides an integrated power-management soluTIon for a single PC Card. All of the discrete power MOSFETs, a logic secTIon, current limiTIng, and thermal protecTIon for PC Card control are combined on a single integrated circuit, using the Texas Instruments LinBiCMOS™ process. The circuit allows the distribution of 3.3-V, 5-V, and/or 12-V card power, and is compatible with many PCMCIA controllers.
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 the PC Card. controllers.
