3.2 Without External FET VOUT/DP_IN/DM-IN Short-to-VBAT Application

This application is the same as the application in Section 3.1, this case also can be summarized as the following:

Application 1: Figure 3-13 shows the test setup. First, power off the power supply, then short VOUT/DP_IN/DM_IN to VBAT. The state at each point is the following:

  • VBAT = 14.5 V
  • VIN = 0 V
  • EN = VIN
  • VOUT = 0 V
  • IOUT = 0 A

Application 2: Figure 3-14 shows the test setup. First, short VOUT/DP_IN/DM_IN to VBAT, then power on the power supply.
