description
The TPS2214A and TPS2216A PC Card power-interface switches provide 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 single integrated circuits. These low-cost devices allow 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 TPS2214A and TPS2216A feature 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. These devices also have 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 these products include: notebook computers, desktop computers, personal
digital assistants (PDAs), digital cameras, and bar-code scanners.
The TPS2216A is backward-compatible with the TPS2202A, TPS2206, and TPS2216. The TPS2214A is
backward-compatible with the TPS2214.
