4.1.2 Communication Verification

Use the following steps for I2C communication verification. Assuming the jumper settings in Table 3-2 have been followed, the I2C address for U1 is 0x65, and the I2C address for U2 is 0x67. If R29 and R32 have been populated, then the I2C address for U4 is 0x6B.

  1. In BQStudio, click Field View and select the I2C address for U1 (0x65).
  2. Click Read Register at the top of the page. Device ACK OK appears at the top right.
  3. Verify that VAC1 and VOUT are reported as Present.

  4. Change the following register settings:
    • Disable the watchdog timer
