7.4.3 Disabled

The device is disabled under any of the following conditions:

  • |VEN| < |V(HI)|
  • The device junction temperature is greater than the thermal shutdown temperature.

#GUID-502EDDE0-F194-4FF9-B8AF-5AB9BDA868B8/SBVS2359568 shows the conditions that lead to the different modes of operation.
