2.4.2 I2C Register Communication Verification

Use the following steps for communication verification :

  1. In the EVM software, click the button
    • Verify that the GUI reads in the top right corner.
      Note:

      If the device reads verify Section 2.2 and Section 2.4.1 steps have been followed.

  2. In the Field View (see Figure 2-4), make the following changes as necessary:
    • Set
    • Set
    • Set

      • Note that BQ25622 ILIM pin resistor clamps the input current to 1-A unless that pin is disabled using GUID-20221111-SS0I-ZCKT-VML0-RWZDMTPJN61L-low.png.
