    FAQ

    • Super interesting device! Only couple questions:
      1) on page 13 of the datasheet the last sentence says "MPPT configuration pins MPPT[1:0] are connected
      to GND and configured to 70%" but table 6 shows that with MPTT[1:0] set to 0 0 mptt ratio is set to 90%
      2) the example circuit on page 13 shows the SET_OD, SET_CR, SET_OC shorted together and left floating, but on page 11 is said that these pins should be left floating ( and I assume not connected together ) when using predefined modes, are both ok?

      The MPPT configuration of the DFM8001 is not efficient at RF energy harvesting, but can still harvest RF energy. Our R&D team is working on a variety of new weak energy harvesting products to efficiently harvest all types of environmental energy.
