Hi, We are working on a new design according to i.MX53QSB-R. I have 2 questions for Battery Interface & Coulomb Counter on MC34708.


question 1


I think that I don't have to connect all. Don't I need to tie only BP and BATT to VCC_BP?


question 2

TRICKLESEL tied to VCOREDIG and PRETMR tied to GND. But I don't use Trickle Charge & Standalone Charge.

Is it any problem if floating PRETMR and TRICKLESEL?


What do you think?
