Overview
The TPT24857 is an SD 3.0 spec-compliant memory card voltage-level translator with bidirectional control. It is designed to translate voltage between voltage 1.8V to 3.0V in card side and 1.2V to 1.8V in host side.
The device supports SD 3.0 SDR104 in high speed mode, and covers down to SDR50, DDR50, SDR25, SDR12 & SD 2.0 (50MHz and 25MHz) modes. The TPT24857 has an integrated voltage regulator to supply the card-side I/Os, can support 100mA peak current with an auto-enable function. The device also has the EMI filters and support robust ESD protections: 10kV IEC contact ESD.
TPT24857 is available in WLCSP20 with 0.4mm pitch package, and is characterized from –40°C to +85°C.
