  • The ST high voltage BST capacitance controller STHVDAC-253C7 is a high voltage Digital to Analog Converter (DAC), specifically designed to control and meet the wide tuning bias voltage requirement of the BST tunable capacitances.

    It provides three independent high voltage outputs to control three different capacitances. It is fully controlled through an RFFE serial interface.
    BST capacitances are tunable capacitances intended for use in mobile phone application, and dedicated to RF tunable application. They are controlled through a bias voltage ranging from 0 to 24 V. The implementation of BST tunable capacitance in mobile phones enables a significant improvement in terms of radiated performance, making the performance almost insensitive to external environment.

    Key Features

    • Dedicated controller to bias BST tunable capacitances
    • Turbo and Glide Modes for optimal system performance
    • Integrated boost converter with 3 programmable outputs (from 0 to 24 V)
    • Low power consumption and high accuracy thanks to production trimming
    • MIPI RFFE v2.0 serial interface 1,8 V with extended frequency range up to 52 MHz
    • Synchronous reads support (sRead)
    • 3 USID support in order to control 3 antennas with a single device
    • GPIO for Register swap to support DPDT switching and USB cable plugged in
    • Available in 350 microns pitch WLCSP for stand-alone or SiP module integration
    • WLCSP package is not sensitive to moisture (MSL = 1)
