NCN4557
1.8 V/3.0 V Dual SIM/SAM/
Smart Card Power Supply
and Level Shifter
The NCN4557 is a dual interface analog circuit designed to
translate the voltages between SIM, SAM or Smart Cards and a
microcontroller (or similar control device). It integrates two LDOs
for power conversion and three level shifters per channel allowing
the management of two independent chip cards. The device fulfills
the ISO7816 and EMV smart card interface requirements as well as
the GSM and 3G mobile standard. Due to a built鈭抜n sequencer, the
device enables automatic activation and deactivation. Through the
ENABLE pin a low current shutdown mode can be activated
extending the battery life.
The card power supply voltage (1.8 V or 3.0 V) and the card socket
A or B are selected using two dedicated pins (SEL0 & SEL1).
