Product Overview

The LTC1555LEGN-1.8#PBF is a SIM Power Supply and Level Translator provides power conversion and level shifting needed for low voltage GSM and WCDMA cellular telephones to interface with either 1.8V, 3V or 5V subscriber identity modules (SIMs). The part contains a patented buck/boost charge pump DC/DC converter that delivers a regulated VCC supply voltage to the SIM card. Input voltage may range from 2.6 to 6V allowing direct connection to the battery. Internal level translator allows controllers to operating with supplies as low as 1.425V to interface with 1.8, 3 and 5V SIMs. A soft-start feature limits inrush current at turn-on, mitigating start-up problems that may result when the input is supplied by another low-power DC/DC converter. Battery life is maximized by 32µA operating current and 1µA shutdown current. Board area is minimized by the miniature 16-pin narrow SSOP packages and the need for only three small external capacitors.
  • Short-circuit and overtemperature protected
  • Meets all ETSI and IMT-2000 SIM interface requirements
  • 32µA Very low operating current
  • <1µA Very low shutdown current
  • >10kV ESD on All SIM contact pins
