description
? The TPS2214 is identical to the TPS2216 in all respects
except packaging and pin assignments.
NC – No internal connection
The TPS2214 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 TPS2214 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 TPS2214 include: notebook computers, desktop computers, personal
digital assistants (PDAs), digital cameras, and bar-code scanners.
