hi,

at BQ24070 how do I calculate the Rddpm and Rset ?

I do not understand the spec, 

charging current need to be 2A, the load is connect directly to the battery pins and not to the output pins, we do the switching between sources else where.

    Equations 1 and 2 on page 12 show to compute RDDPM.

    Equation 4 on page 17 shows how to compute RISET.

    The variables for each are on pages 4-5.

    Maximum charge current is 1.5A.  Maximum charge current + out current is 2A.
