IP4855CX25

SD 3.0-compliant memory card integrated dual voltage level translator with EMI filter and ESD protection

The device is an SD 3.0-compliant 6-bit bidirectional dual voltage level translator. It is designed to interface between a memory card operating at 1.8 V or 2.9 V signal levels and a host with a fixed nominal supply voltage of 1.2 V to 3.3 V. The device supports SD 3.0 SDR50, DDR50, SDR25, SDR12 and SD 2.0 high-speed (50 MHz) and default-speed (25 MHz) modes. The device has an integrated voltage selectable low dropout regulator to supply the card-side I/Os, built-in EMI filters and robust ESD protections (IEC 61000-4-2, level 4).

Features and benefits

  • Supports up to 100 MHz clock rate
  • Feedback channel for clock synchronization
  • SD 3.0 specification-compliant voltage translation to support SDR50, DDR50, SDR25, SDR12, high-speed and default-speed modes
  • 50 mA low dropout voltage regulator to supply the card-side I/Os
  • Low power consumption by push-pull output stage with break-before-make architecture
  • Integrated pull-up and pull-down resistors: no external resistors required
  • Integrated EMI filters suppress higher harmonics of digital I/Os
  • Integrated 8 kV ESD protection according to IEC 61000-4-2, level 4 on card side
  • Level shifting buffers keep ESD stress away from the host (zero-clamping concept)
  • 25-ball WLCSP; pitch 0.4 mm

Applications

  • Smartphones
  • Mobile handsets
  • Digital cameras
  • Tablet PCs
  • Laptop computers
  • SD, MMC or microSD card readers

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
