Features
Description
„Fully Integrated VCC and Vpp Switching for Dual
The G570 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 (IC). The circuit allows the distribution of 3.3V, 5V,
and/or 12V card power by means of the Serial interface. The current-limiting feature eliminates the need
for fuses, which reduces component count and improves reliability.

The G570 features a 3.3V low voltage mode that allows
for 3.3V switching without the need for 5V supply. This
facilitates low power system designs such as sleep
mode and pager mode where only 3.3V is available.
The G570 incorporates a reset function, selectable by
one of two inputs, to help alleviate system errors. The
reset function enables PC card initialization concurrent
with host platform initialization, allowing a system reset.
Reset is accomplished by grounding the VCC and VPP
(flash-memory programming voltage) outputs, which
discharges residual card voltage.

resistance of the switch and thus produce no additional voltage losses. Second, when an overcurrent
condition is detected, the G570 asserts a signal at
OC that can be monitored by the microprocessor to
initiate diagnostics and/or send the user a warning
message. In the event that an overcurrent condition
persists, causing the IC to exceed its maximum
junction temperature, thermal-protection circuitry
activates, shutting down all power outputs until the
device cools to within a safe operating region.
Overview
PC Cards were initially introduced as a means to add
EEPROM (flash memory) to portable computers with
limited on-board memory. The idea of add-in cards
quickly took hold; modems, wireless LANs, Global
Positioning Satellite (GPS), 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. To this end, the
PCMCIA was established, comprised of members
from leading computer, software, PC Card, and
semiconductor manufactures. One key goal was to
realize the “plug-and play” concept. Cards and hosts
from different vendors should be compatible—able to
communicate with one another transparently.
12V Supply Not Required
Most PC Card switches use the externally supplied
12V VPP power for switch-gate drive and other chip
functions, which requires that power be present at all
times. The G570 offers considerable power savings by
using an internal charge pump to generate the required higher voltages from 5V or 3.3V input; therefore,
the external 12V supply can be disable except when
needed for flash-memory functions, thereby extending
battery lifetime. Do not ground the 12V input if the 12V
input is not used. Additional power savings are realized by the G570 during a software shutdown in which
quiescent current drops to a typical of 2µA.
PC Card Power Specification
System compatibility also means power compatibility.
The most current set of specifications (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 68 terminals of the PC Card
connector. This power interface consists of two VCC,
two VPP, and four ground terminals. Multiple VCC and
ground terminals minimize connector-terminal and line
resistance. The two VPP terminals were originally
specified as separate signals but are commonly tied
together in the host to form a single node to minimize
voltage losses. Card primary power is supplied
through the VCC terminals; flash-memory programming
and erase voltage is supplied through the VPP terminals.
3.3V Low Voltage Mode
The G570 operates in 3.3V low voltage mode when
3.3V is the only available input voltage (VI(5V)=0).This
allows host and PC Cards to be operated in low power
3.3V only modes such as sleep modes or pager
modes. Note that in this operation mode, the G570
derives its bias current from the 3.3V input pin and
only 3.3V can be delivered to the Card. The 3.3V
switch resistance increases, but the added switch resistance should not be critical, because only a small
amount of current is delivered in this mode.
Overcurrent and Over-Temperature Protection
PC Cards are inherently subject to damage that can
result from mishandling. Host systems require protection against short-circuited cards that could lead to
power supply or PCB-trace damage. Even systems
robust enough 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. Most hosts include fuses for
protection. However, the reliability of fused systems is
poor, as blown fuses require troubleshooting and repair, usually by the manufacturer.
Voltage Transitioning Requirement
PC Cards, like portables, are migrating from 5V to
3.3V to minimize power consumption, optimize board
space, and increase logic speeds. The G570 is designed to meet all combinations of power delivery as
currently defined in the PCMCIA standard. The latest
protocol accommodates mixed 3.3V/5V systems by
first powering the card with 5V, then polling it to determine its 3.3V compatibility. The PCMCIA specification requires that the capacitors on 3.3V compatible
cards be discharged to below 0.8 V before applying
3.3V power. This ensures that sensitive 3.3V circuitry
is not subjected to any residual 5V charge and functions as a power reset. The G570 offer a selectable
VCC and VPP ground state, in accordance with PCMCIA
3.3V/5V switching specifications, to fully discharge the
card capacitors while switching between VCC voltage.
The G570 takes a two-pronged approach to overcurrent protection. First, instead of fuses, sense FETs
monitor each of the power outputs. Excessive current
generates an error signal that linearly limits the output
current, preventing host damage or failure. Sense
FETs, unlike sense resistors or polyfuses, have an
added advantage in that they do not add to the series

Output Ground Switches
Several PCMCIA power distribution switches on the
market do not have an active grounding FET switch.
These devices do not meet the PC Card specification
requiring a discharge of VCC within 100ms. 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. A method commonly shown to
alleviate this problem is to add to the switch output an
external 100kΩ resistor in parallel with the PC Card.
Considering that this is the only discharge path to
ground, a timing analysis show that the RC time constant delays the required discharge time to more than
2 seconds. The only way to ensure timing compatibility
with PC Card standards is to use a power-distribution
switch that has an internal ground switch, like that of
the G570, or add an external ground FET to each of
the output lines with the control logic necessary to select it.
G570
RESET or RESET Inputs
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 as the host by applying a low impedance to the VCC and VPP terminals.
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 RESET or RESET
input closes internal switches S1, S4, S7, and S10
with all other switches left open (see G570 control
logic table). The G570 remains in the low impedance
output state until the signal is deasserted and further
data is clocked in and latched. RESET or RESET is
provided for direct compatibility with systems that use
either an active-low or active-high reset voltage supervisor. The unused pin is internally pulled up or down
and should be left unconnected.
Overcurrent and Thermal Protection
The G570 uses sense FETs to check for overcurrent
conditions in each of the VCC and VPP outputs. Unlike
sense resistors or polyfuses, these FETs do not add to
the series resistance of the switch; therefore, voltage
and power losses are reduced. Overcurrent sensing is
applied to each output separately. When an overcurrent condition is detected, only the power output affected is limited; all other power outputs continue to
function normally. The OC indicator, normally a logic
high, is a logic low when any overcurrent condition is
detected, providing for initiation of system diagnostics
and/or sending a warning message to the user.
In summary, the G570 is a complete single-chip
dual-slot PC Card power interface. It meets all currently defined PCMCIA specifications for power delivery in 5V, 3.3V, and mixed systems, and offers a serial
control interface. The G570 offers functionality, power
savings, overcurrent and thermal protection, and fault
reporting in one 30 pin SSOP surface-mount package
for maximum value added to new portable designs.
Power Supply Considerations
The G570 has multiple pins for each of its 3.3V, 5V,
and 12V power inputs and for switched VCC outputs.
Any individual pin can conduct the rated input or output current. Unless all pins are connected in parallel,
the series resistance is significantly higher than that
specified, resulting in increased voltage drops and lost
power. Both 12V inputs must be connected for proper
VPP switching; it is recommended that all input and
output power pins be paralleled for optimum operation.
During power up, the G570 controls the rise time of
the VCC and VPP outputs and limits the current into a
faulty card or connector. If a short circuit is applied
after power is established (e.g., hot insertion of a bad
card), current is initially limited only by the impedance
between the short and the power supply. In extreme
cases, as much as 10A to 15A may flow into the short
before the current limiting of the G570 engages. If the
VCC or VPP outputs are driven below ground, the G570
may latch nondestructively in an off state. Cycling
power will reestablish normal operation.
Although the G570 is fairly immune to power input
fluctuations and noise, it is generally considered good
design practice to bypass power supplies typically with
a 1µF electrolytic or tantalum capacitor paralleled by a
0.047µF to 0.1µF ceramic capacitor. It is strongly recommended that the switched VCC and VPP outputs be
bypassed with a 0.1µF or larger capacitor; doing so
improves the immunity of the G570 to electrostatic
discharge (ESD). Care should be taken to minimize
the inductance of PCB traces between the G570 and
the load. High switching currents can produce large
negative-voltage transients, which forward biases
substrate diodes, resulting in unpredictable performance. Similarly, no pin should be taken below –0.3V.
Overcurrent limiting for the VCC outputs is designed to
activate, if powered up, into a short in the range of
0.8A to 2.2A. The VPP outputs limit from 120mA to
400mA. The protection circuitry acts by linearly limiting
the current passing through the switch rather than initiating a full shutdown of the supply. Shutdown occurs
only during thermal limiting.
Thermal limiting prevents destruction of the IC from
overheating if the package power-dissipation ratings are
exceeded. Thermal limiting disables all power outputs
(both A and B slots) until the device has cooled.
