3.2.2 DP_IN/DM_IN Short-to-VBAT Application

  • Application 1: Power off the power supply, then short DP_IN/DM_IN to VBAT. Figure 3-16 and Figure 3-17 show the test results.
  • Application 2: Short DP_IN/DM_IN to VBAT, then power on the power supply. Figure 3-18 and Figure 3-19 show the test results.
  • Application 3: Short DP_IN/DM_IN to VBAT, power on the power supply, then enable EN. Figure 3-20 and Figure 3-21 show the test results.
