DESCRIPTION
12-V Supplies Can Be Disabled Except During
12-V Flash Programming
The TPS2206A PC CardBus power-interface switch
provides an integrated power-management solution for
two PC Card sockets. This 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 are set for the peak and average current
requirements stated in the PC Card specification, and
are optimized for cost.
