3.3.2.4 Power and Diagnostic Settings

Texas Instruments created two additional modes to regulate the power delivered to the LCS, identify the faults of LCS, and check for an open load condition on the output. Refer to Section 3.2.5 for more details on the diagnostic modes.

The Power mode consists of two bursts (20 and 21). Burst 20 corresponds to Power Region 1, which is calibrated using Cal Region 1. Burst 21 corresponds to Power Region 2, which is calibrated using Cal Region 2. For convenience, the calibrated power values appear in the Power Parameters section of the GUI shown on the right side of Figure 4-18. The remaining settings are described in the Table 4-14.

The System Fault mode is a single burst which corresponds to Cal Region System Fault. The settings available for this mode are shown on the left side of Figure 4-18 and described in the Table 4-15.
