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.

End-equipment applications for the TPS2216 include: notebook computers, desktop computers, personal

digital assistants (PDAs), digital cameras, and bar-code scanners.

The TPS2216 is backward-compatible with the TPS2202A and TPS2206.
