DESCRIPTION
The TPS2228 and TPS2221 PC card power interface
switches provide an integrated power management
solution for both dual and single PC card sockets. The
TPS2228 is a dual-slot power interface switch for serial
PCMCIA controllers. The TPS2221 is a single-slot power
interface switch for parallel PCMCIA controllers. These
power interface switches support the distribution of 3.3 V,
5 V and 1.8 V to the PC card slot while providing
current-limiting protection with overcurrent reporting.

APPLICATION INFORMATION
OVERVIEW
PC cards were initially introduced as a means to add
EEPROM (flash memory) to portable computers with
limited onboard memory. The idea of add-in cards quickly
took hold; modems, wireless LANs, GPS systems,
multimedia, and hard-disk versions were soon available.
As the number of PC card applications grew, the
engineering community quickly recognized the need for a
standard to ensure compatibility across platforms. As a
result, the PCMCIA (Personal Computer Memory Card
International Association) was established, comprised of
members from leading computer, software, PC card, and
semiconductor manufacturers. One key goal was to
realize the plug-and-play concept, so that cards and hosts
from different vendors could communicate with one
another transparently.
PC CARD POWER SPECIFICATION
The current PC card standard set forth by the PCMCIA
committee states that power is to be transferred between
the host and the card through eight of the PC card
connector’s 68 terminals. This power interface consists of
two VCC, two VPP/VCORE, and four ground terminals.
Multiple power and ground terminals minimize
connector-terminal and line resistance. The two Vpp/
Vcore terminals were originally specified as separate
signals, but the host is no longer required to provide
separate programmable voltages on each pin. Primary
power for the card is supplied through the VCC terminals;
flash- memory programming and erase voltage is supplied
through the VPP/VCORE terminals. The VPP/VCORE
terminals are also intended to be used as a supplemental
source of power, such as a core voltage for integrated
circuits.
OVERCURRENT AND OVER TEMPERATURE
PROTECTION
PC cards are inherently subject to damage caused by
mishandling. Host systems require protection against
short-circuited cards that could lead to power supply or
PCB trace damage. Even systems sufficiently robust to
withstand a short circuit would still undergo rapid battery
discharge into the damaged PC card, resulting in the
rather sudden and unacceptable loss of system power.
The TPS2228/2221 power interface switch is designed to
respond quickly to an overcurrent condition to protect the
system. During an overcurrent event, the current limit
circuit of the TPS2228/2221 generates an internal error
signal that linearly limits the output current of the affected
output. The propogation delay associated with activating
the current-limit circuit has an effect on the amount of
current initially delivered to the output. During this time, the
16
input voltage to the switch may droop a small amount. The
amount of voltage droop is system dependent. Power
supply bulk capacitors play an important role in minimizing
this voltage droop.
Overcurrent sensing is applied to each output separately.
As a result, only the affected output is current-limited
during an overcurrent event. The TPS2228/2221 also has
an overcurrent status output (OC) that is asserted low to
provide feedback that an overcurrent condition has
occurred.
The TPS2228/2221 has two thermal shutdown circuits.
The higher thermal shutdown circuit protects the device
from a high junction temperature condition. In the event
that the junction temperature exceeds a minimum of
155°C, the higher thermal shutdown circuit turns off all
switches to protect the device. Normal switch operation
resumes when the junction temperature cools down
approximately 10°C.
In the event of an overcurrent condition, the lower thermal
shutdown circuit activates when the junction temperature
exceeds a minimum of 120°C. On the TPS2221, this lower
thermal shutdown circuit disables both the VCC and the
VPP/VCORE switches once the junction temperature
exceeds the lower thermal trip point. On the TPS2228,
only the channel in overcurrent (either AVCC and
AVPP/VCORE, or BVCC and BVPP/VCORE) is disabled. For
both the TPS2221 and the TPS2228, normal operation of
the switches resumes once the junction temperature cools
down approximately 10°C. This cycle continues until the
overcurrent condition is removed.
VOLTAGE TRANSISTIONING REQUIREMENT
PC cards, like portables, are migrating from 5 V to 3.3 V
and even 1.8 V to minimize power consumption, optimize
board space, and increase logic speeds. The
TPS2228/2221 power interface switch is designed to meet
all combinations of power delivery as currently defined in
the PC card standard. The latest protocol accommodates
mixed 3.3 V/ 5 V systems by first powering the card with
5 V, then polling it to determine if it is compatible with 3.3-V
power. The PC card standard requires that the capacitors
on 3.3-V compatible cards be discharged to below 0.8 V
before applying 3.3 V power. This ensures that sensitive
3.3-V circuitry is not subjected to any residual 5-V charge
and functions as a power reset. The PC card standard
requires that VCC be discharged within 100 ms. PC card
resistance can not be relied on to provide a discharge path
for voltages stored on PC card capacitance because of
possible high-impedance isolation by power-management
schemes. The TPS2228/2221 power interface switch
includes discharge transistors on all VCC and VPP/VCORE
outputs to meet the specification requirement.

Next, sum the power dissipation and calculate the junction
temperature:
SHUTDOWN MODE
In the shutdown mode, each of the VCC and VPP/VCORE
outputs is forced to a high-impedance state (Hi-Z). In this
mode, the chip quiescent current is reduced to conserve
battery power.
ǒ
TJ + S P
D
R
qJA
Ǔ ) TA
POWER SUPPLY CONSIDERATIONS
Where RθJA is the inverse of the derating factor in the
dissipation rating table.
The TPS2228/2221 power interface switch has multiple
pins for each of its power inputs and for the switched VCC
outputs. The two 1.8VIN pins must be connected together
externally. It is recommended that all input and output
power pins be parallel connected for optimum operation.
Compare the calculated junction temperature with the
initial temperature estimate. If the temperatures are not
within a few degrees of each other, recalculate using the
calculated temperature as the initial estimate.
To increase the noise immunity of the TPS2228/2221
power interface switch, the power supply inputs should
have a minimum of 1µF electrolytic or tantalum bypass
capacitor connected in parallel with a 0.047 µF to 0.1 µF
ceramic capacitor. It is strongly recommended that the
switched outputs be bypassed with a 0.1 µF or larger
ceramic capacitor. Doing so improves the immunity of the
TPS2228/2221 power interface switch to electrostatic
discharge (ESD). Care should be taken to minimize the
inductance of PCB traces between the TPS2228/2221
power interface switch and the load.
RESET
To ensure that cards are in a known state after power
brownouts or system initialization, the PC cards should be
reset at the same time via the host, by applying low
impedance paths from VCC and VPP/VCORE terminals to
ground. A low-impedance output state allows discharging
of residual voltage remaining on PC card filter
capacitance, permitting the system (host and PC cards) to
be powered up concurrently. The active low RESET input
will program all outputs to 0 V. The TPS2228 power
interface switch remains in the low-impedance output
state until the signal is deasserted and new data is
received. For the TPS2228, the input serial data cannot be
latched during reset mode.
CALCULATING JUNCTION TEMPERATURE
The switch resistance, rDS(on), is dependent on the
junction temperature, TJ, of the die. The junction
temperature is dependent on both rDS(on) and the current
through the switch. To calculate TJ, first find rDS(on) from
Figures 10 through 14 using an initial temperature
estimate about 50°C above ambient. Then calculate the
power dissipation for each switch, using the formula:
PD + r
DS(on)
LOGIC INPUTS AND OUTPUTS
For the TPS2228, the serial interface consists of DATA,
CLOCK, and LATCH signals. The data is clocked in on the
positive leading edge of the clock (see Figure 2). The 11-bit
(D0−D10) serial data word is loaded during the positive
edge of the latch signal. The latch signal should occur
before the next positive leading edge of the clock.
The serial interface of the TPS2228 power interface switch
is designed to be compatible with serial-interface PCMCIA
controllers and current PCMCIA and Japan Electronic
Industry Development Association (JEIDA) standards.
For the TPS2221, the parallel interface consists of four bits
(D3:D0). These four bits must be driven continuously to
select the desired voltage outputs based on the input bit
pattern. During power up, these inputs can be connected
to an external pulldown resistor to ensure that the outputs
are at zero volts, especially if the device driving these
inputs is in a high impedance state while initializing.
An overcurrent output (OC) is provided to indicate an
overcurrent or over-temperature condition in any of the
VCC and VPP/VCORE outputs as previously discussed.
ESD PROTECTION
All TPS2228/2221 power interface switch inputs and
outputs incorporate ESD-protection circuitry designed to
withstand a 2-kV human-body-model discharge as defined
in MIL-STD-883C, Method 3015. The VCC and VPP/
VCORE outputs can be exposed to potentially higher
discharges from the external environment through the PC
card connector. Bypassing the outputs with 0.1-µF
capacitors protects the devices from discharges up to
10 kV.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
