Application 1: Figure 3-1 shows the test setup. The state at each point is power supply off (Vout = 0 V, LS_GD is low, and Q1 is off). Short DP_IN/DM_IN to VBAT. The voltage of DP_IN/DM_IN rushes to the same height as VBAT. Figure 3-7 and Figure 3-8 show the test results.
Application 2: Figure 3-2 shows the test setup. DP_IN/DM_IN shorts to VBAT. The input voltage and DP_IN/DM_IN voltage are rushed to the same height as VBAT together. Figure 3-9 and Figure 3-10 show the test results.
Application 3: Figure 3-3 shows the test setup. First, short DP_IN/DM_IN to VBAT and power on the power supply, then enable EN. Figure 3-11 and Figure 3-12 show the test results.
