SGM4558
Dual SIM/Smart Card
Power Supply and Interface
GENERAL DESCRIPTION
FEATURES
The SGM4558 is used for power conversion and level
translation of the signal in the application of SIMs for
mobile phones. Also, it can be used for the applications
of 1.8V or 3.3V SIMs, which is powered by its internal
LDOs from 2.7V to 5.5V input signal. The value of the
output voltage can be controlled with the voltage
selection pins of the SGM4558 with the maximum load
current of 250mA. The function of the channel selection
pins is that it can be used to determine the open
condition of the specific channel. The two SIM cards
can be powered by the SGM4558 at once with the
control of the enable pins for each channel, and the fast
translation can be made from channel A to channel B.
● Controlling of Two SIM or Smart Cards with the
Internal Power Management
● Both Connected Cards are Powered by the
1.8V/3.3V Power Supply
● Two LDOs Support up to 250mA Loading
● Powering Two SIM or Smart Cards at the Same
Time
● Quick Switching from One Channel to Another
● Automatic Level Translation
● Fast Rising Time for the Signals
● Protecting Mechanism for Any Fault Conditions
● Mechanism which can Activate/Deactivate the
Sequence
● Extreme Low Supply Voltage and Shutdown
Current
The level translator integrated on the SGM4558 can
boost the input signal which is powered by 1.4V to 1.8V
or 3V interface. If the supply voltage is below 3.3V, the
lifespan of the battery can be enhanced as the 90μA
operating current and 2μA shutdown current.
● -40℃ to +85℃ Operating Temperature Range
● Available in a Green TQFN-3×3-20L Package
APPLICATIONS
The SGM4558 is available in a Green TQFN-3×3-20L
package. It operates over an ambient temperature
range of -40℃ to +85℃.

ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

Card Socket. Both VCCA and VCCB pins should be connected to the power supply pin of the SIM
cards respectively. Also, the voltage of VCCA/VCCB which is controlled by the enable pin of the
SGM4558 can be set to 1.8V or 3V.

Card Socket. Both CLKA and CLKB pins of the SGM4558 should be connected to the card
socket of the SIM cards respectively. Also, these two pins are derived by the CLKIN, which can
be level shifted. If VCCA and VCCB obtain its corrected values, both CLKA and CLKB will start to
operate with the connected SIM cards. The pin will be low or left active through CLKRUNA,
CLKRUNB pins if the card socket is not detected by the SGM4558.

Card Socket. These two pins should be connected to the associated pins of the card socket.
When the SIM card is selected, the I/O pins of the SGM4558 can transmit or receive the
information from the DATA pin. If VCCA and VCCB obtain its corrected values, both I/OA and I/OB

Microcontroller Side Bidirectional Data Input/Output Pin. The DATA pin can select a card at a
time. There is a weak current source integrated inside the pin. Therefore, the output of the
controller can be open-drain and it remains high state during shutdown mode, while DVCC must
be operated during the progress.
