description

The TPS2212 PC Card power-interface switch provides an integrated power-management solution for a single
low power PC Card. All of the discrete power MOSFET s, a logic section, current limiting, and thermal protection
for PC Card control are combined on a single integrated circuit, using the Texas Instruments LinBiCMOS
process. The circuit allows the distribution of 3.3-V , 5-V, and/or 12-V card power , and is compatible with many
PCMCIA controllers. The current-limiting feature eliminates the need for fuses, which reduces component count
and improves reliability. Current-limit reporting can help the user isolate a system fault to the PC Card.

The TPS2212 features a 3.3-V low-voltage mode that allows for 3.3-V switching without the need for 5 V . Bias
power can be derived from either the 3.3-V or 5-V inputs. This facilitates low-power system designs such as
sleep mode and pager mode, where only 3.3 V is available.

End equipment for the TPS2212 includes notebook computers, desktop computers, personal digital assistants
(PDAs), digital cameras, and bar-code scanners. This device is well suited for those applications which need to
limit the power provided to the PC card due to power supply constraints. In many applications, such as palm
computers, the system cannot allocate more than 200 mA of current to a PC card slot. For these lower power
applications, the TPS2212 provides the same advanced level of protection as the TPS221 1 provides for higher
power applications.
