2.4.4 Bypass Mode Charge Verification

Use the following steps to verify battery charging in bypass mode.

  1. Make sure the steps in Section 2.4.1 and Section 2.4.2 have been followed.
  2. Set PS1 to 4.1 V. Load #1 can be kept at 4.0 V.
  3. Make sure the "Enable Charge" box is not selected. Then, click "Enable Bypass Mode".

  4. Click "Enable Charge". After enabling charge, the output current flowing into Load #1 should be approximately equal to the input current flowing out of PS1.
  5. Change the charge current:
    By increasing the input voltage, the output current should increase together with the input current. The output current should always be approximately equal to the input current.
  6. To stop charging, deselect the "Enable Charge" box. The input current and the output current should both fall to zero.
