INTERFACE POWER SWITCH FOR LOW POWER PC CARD SLOTS
Quick Detail:
SINGLE-SLOT, PARALLEL INTERFACE POWER SWITCH FOR LOW POWER PC CARD
SLOTS
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 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 TPS2211
provides for higher power applications
