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. This device allows the distribution of 3.3-V, 5-V, and/ or 12-V power to the card. The current-limiting feature eliminates the need for fuses. Currentlimit reporting can help the user isolate a system fault. The TPS2216 features a 3.3-V low-voltage mode that allows for 3.3-V switching without the need for 5-V power. This fea...
