2.4.2 Communication Verification

Use the following steps for communications verification:

  1. In the TI Charger GUI, select the device to be evaluated, once directed, the software will be directed to Home page. The connection status should display as Connected.
    Note:

    If the device is not communicating and does not connect, verify that Section 2.2 and Section 2.4.1 steps have been followed. Verify the voltage across TP41 (PULLUP) and TP49 (AGND) is approximately 3.3 V.

  2. Select Menu in the top left of the screen. Note the names of the pages and the associated icons.
  3. Prepare the charge mode charger register settings in the following way if not already set there by default:
    • On the Quick Start page below the Quick Start section
      • Set Watchdog Timer to "Disabled"
      • Set Charge Current to "0.500 A"
      • Set Charge Voltage to "8.400 V"
    • On the Charger Configuration page below the Charging Configuration section
      • Set Precharge current to "0.240 A"
      • Set VSYSMIN to "7.000 V"
    • On the Charger Configuration page below the Input Configuration section
      • Set IINDPM to "3.000 A"
      • Set ABS VINDPM to "6.000 V"
    • On the Chip Configuration page below the Chip Configuration section
      • Check the ShipFET Present? box
