General description

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, microSD and MultiMediaCard (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 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.
