2.3.3 Fast Charge Mode Verification

  1. Change Load #1 to 3.7 V and take measurements as follows:
    1. Measure → VBAT (BAT-TP5 and PGND-TP11) = 3.7 V ± 0.1 V
    2. Observe → STAT LED (D2) on
    3. Measure → IBAT for respective battery charger IC from Table 2-2
      Table 2-2 Fast Charge Current Measurement
