NCN4555MNR2G

NCN4555MNR2G is a SIM card power supply and level shifter. It is a level shifter analogue circuit designed to translate the voltages between a SIM Card and an external microcontroller or MPU. The device fulfils 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 (active high) 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). Typical application includes SIM card interface circuit for 2G, 2.5G and 3G mobile phones, identification module, smart card readers, wireless PC cards.

• Operating voltage range from 1.6 to 5.5V (-40°C to +85°C)
• 175mA maximum short circuit current (SIM-VCC shorted to ground, TA=25°C)
• Input voltage range from 0 to VDD (STOP (active high), MOD-VCC, RST, CLK, I/O)
• Input current range from -100 to 100nA (STOP (active high), MOD-VCC, RST, CLK)
• 16 lead QFN package, operating ambient temperature range from -40 to +85°C
