Use the following steps to enable the BQ25308 EVM test setup:

  1. Make sure Section 2.3 steps have been followed.
  2. Turn on PS1.
    • Measure→ VPMID (PMID-TP2 and PGND-TP10) = 5.00V ± 0.3V.
    • Completely disconnect PS1 from J2 if different voltage value is seen on PMID.
      Note: Completely disconnect Load #1 from BATTERY connections if different value is seen.
