2.4.3 Charger Mode Verification

Use the following steps for charger mode verification:

  1. PS1 should be on from Section 2.4.1. In the EVM software, click GUID-A2D5000D-CD07-46F6-A2BF-9D87705B91D7-low.gif twice.
    • Verify that all Fault statuses read "Normal"
      GUID-A11B7AC2-30C7-4044-8C5D-B5B9CED63F30-low.png
    • Verify → STAT LED (D5) is ON
  2. Enable Load #1 (see Section 2.2) and take measurements as follows:
    • Measure → VSYS (SYS-TP17 and PGND-TP30) = 3.65V ±0.3V
    • Measure → VBAT (BATTERY-TP16 and PGND-TP30) = 2.5V ±0.2V
    • Measure → IBAT = 240mA ±50mA
  3. Change Load #1 to 3.7V and take measurements as follows:
    • Measure → VSYS (SYS-TP17 and PGND-TP30) = 3.8V ±0.3V
    • Measure → VBAT (BATTERY-TP16 and PGND-TP30) = 3.7V ±0.2V
    • Measure → IBAT = 480mA ±200mA
  4. In the EVM software, set
    • Measure → IIN = 500mA ±200mA
