1. Product profile
1.1 General description
1.2 Features
1.3 Applications
The IP4853CX24 is a device that fully integrates a bidirectional level shifter or voltage
translator, EMI filter and ESD protection diodes. It is specifically designed to be used for
memory card interfaces such as SD, T-flash and Multi Media Card (MMC) memory cards.
The integrated power supply unit supplies memory cards with 2.9 V directly from the
battery. This enables a 1.8 V operating host side device (e.g. a processor interface) to
communicate with a 2.9 V compliant memory card using its integrated level shifter.
Radiation from digital signals in the higher harmonics, close to the typical mobile phone
frequencies, is suppressed by the EMI filter.
The IP4853CX24 is fabricated using monolithic silicon technology in a Wafer-Level
Chip-Scale Package (WLCSP) with 0.4 mm pitch.
