2.3.2 Charge Mode Verification

  1. PS1 should be on from Section 2.3.1.
  2. Enable Load #1.
  3. Adjust R12 potentiometer to increase the charge current limit to 1A
    • Measure → IBAT (current into Load #1) = 1.0A±25mA
    • Record IBAT measurement
  4. Change Load #1 to 2.5V
    • Measure → VSYS (SYS-TP14 and PGND-TP24) = 3.65V±0.3V
    • Measure → IBAT (current into Load #1) = 5% of previous IBAT result ≈ 50mA±15mA
