2.4 Test Points

There are multiple test points (48) on the board that can be used to either measure the associated trace or apply external signals for testing purposes. Table 2-5 shows the test points for the sixteen generic U1 connections and 2 OVP Trigger Thresholds. There are two test points per pin of the IC, which are colored blue.

Test points also connect to VSS, VDD, and GND planes. In addition, there are test points for the fault flag indicator led circuits and OVP Trigger Thresholds.

Table 2-6 shows these test points.
