DESCRIPTION
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 r_DS(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.
The TPS2206A is pin and/or functionally compatible with
the TPS2206, TPS2216, TPS2216A, TPS2226,
TPS2226A, and TPS2228 with a few exceptions, as
shown in the Available Options table.
