NCN4555 1.8V / 3V SIM Card Power Supply and Level Shifter The NCN4555 is a level shifter analog circuit designed to translate the voltages between a SIM Card and an external microcontroller or MPU. A built−in LDO−type DC−DC converter makes the NCN4555 useable to drive 1.8 V and 3.0 V SIM card. The device fulfills the ISO7816−3 smart card interface standard as well as GSM 11.11 and related (11.12 and 11.18) and 3G mobile requirements (IMT−2000/3G UICC standard). With the STOP pin a low current shutdown mode can be activated making the battery life longer. The Card power supply voltage (SIM_VCC) is selected using a single pin (MOD_VCC). Features • Supports 1.8 V or 3.0 V Operating SIM Card • The LDO is able to Supply More than 50 mA under 1.8 V and 3.
