TPT24857 Level Shift -3peak

　　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 1.8 V to 3.0 V in card side and 1.2 V to 1.8 V 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(50 MHz and 25 MHz)modes.The TPT24857 has an integrated voltage regulator to supply the card-side I/Os,can support 100mA peak current with an autoenable 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.
