description
The TPS2216 PC Card power-interface switch
provides an integrated power-management
solution for two PC Cards. 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. Current-
limit 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 feature facilitates low-power
system designs such as sleep modes where only
3.3 V is available. This device also has the ability
to program the xVPP outputs independent of the
xVCC outputs. A standby mode that changes all
output-current limits to 50 mA (typical) has been
incorporated.
