Product Overview

The LTC4555EUD#PBF is a SIM Power Supply And Level Translator provides power conversion and signal level shifting needed for low voltage 2.5 and 3G cellular telephones to interface with 1.8 or 3V subscriber identity modules (SIMs). The part meets all type approval requirements for 1.8 and 3V SIMs and smart cards. The part contains an LDO linear regulator to supply SIM power at either 1.8 or 3V from a 3 to 6V input. The output voltage is selected with a single pin and up to 50mA of load current can be supplied. Internal level translators allow controllers operating with supplies as low as 1.2V to interface with 1.8 or 3V smart cards. Battery life is maximized by 20µA operating current and <1µA shutdown current.
  • Meets all ETSI, IMT-2000 and ISO7816 SIM/smart card interface requirements
  • 20µA Operating current
  • <1µA Logic-controlled shutdown
  • 14kV ESD on all SIM contact pins
