  • RE: UCD9248: How to let the fusion digital power designer know I have a external instrument amplifer to sense output current of the power module

    Resolved
    The UCD9248 current sense signals are intended to come from the IOUT signals on the power modules, like pin 6 on the PTD08A020W module shown in your schematic. One can adjust the gain of the current sense amplifier. Ohms are the unit because the current…

  • PTD08D210W: FLT flag being set from power on

    Part Number: PTD08D210W Other Parts Discussed in Thread: PTD08A020W , UCD9248 , UCD7242 We have an FPGA board design, whose power rail circuitry is heavily based on the Xilinx VC709 architecture, as such we have UCD9248 power controllers and PTD08D210W…
