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 MOSFETs, 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 that need to
limit the power provided to the PC card because of 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 that the TPS2211 provides for
higher-power applications.
