DESCRIPTION
The TPS2204A and TPS2206A PC CardBus
power-interface switches provide an integrated
power-management solution for two PC Card sockets.
The TPS2210A is a single-slot option for this family of
devices. These devices allow 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.
