Product Summary

The TPS2226DB is a Card-Bus power-interface switch provides an integrated power-management solution for two PC Card sockets. The device allows 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 need for fuses. Current-limit reporting helps the user isolate a system fault. The switch rDS(on) and current-limit values have been set for the peak and average current requirements stated in the PC Card specification, and optimized for cost. The applications of the TPS2226DB include Notebook and Desktop Computers, Bar Code Scanners, Digital Cameras, Set-Top Boxes, PDAs.
