− FAULT
− HO=LO=0 (Normal operation)
− HO/LO=1 (Normal operation)
− UNDERVOLTAGE VCC
− SHUTDOWN (SD)
− UNDERVOLTAGE VBS
− FREEZE

Temporary State
− SOFT SHUTDOWN
− START UP SEQUENCE
System Variable
− FLT_CLR
− HIN/LIN
− UV_VCC
− UV_VBS
− DSH/L
− SY_FLT
− FAULT/SD
NOTE 1: A change of logic value of the signal labeled on lines (system variable) generates a state transition.
NOTE 2: Exiting from UNDERVOLTAGE VBS state, the HO goes high only if a rising edge event happens in HIN.
