IP4853CX24
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, 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.
Features
- Darkgreen compliant
- Pb-free, RoHS compliant and halogen free package
- Integrated EMI filters
- Feedback channel for clock synchronization
- Integrated ESD protection according to IEC 61000-4-2, level 4
- WLCSP with 0.4 mm pitch
