State diagram
IR22381QPBF/IR21381Q(PbF)
Stable States
Temporary States
System Variables
− FAULT
− Normal operation
− UNDERVOLTAGE V_CC
− SHUTDOWN (SD)
− UNDERVOLTAGE V_BS
− SOFT SHUTDOWN
− FAULT CLEAR indicates:
LIN1=LIN2=LIN3=0
− HIN/N /LIN/BRIN/N
− UV_VCC
− UV_VBS
− DSH/L, DSB
− 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 V_BS state, the HO goes high only if a falling edge event happens in
HIN/N.
