(typ.2ms)

Notes:

*1 : Diagram shows the prevention of shoot-thru via control logic, however, more dead time must be added to account for switching delay

externally.

*2 : When VDD decreases all gate output signals will go low and cut off all 6 IGBT outputs. When VDD rises the operation will resume

immediately.

*3 : When the upper side voltage at VB1, VB2 and VB3 drops only the corresponding upper side output is turned off. The outputs return

to normal operation immediately after the upper side gate voltage rises.

*4 : When VITRIP exceeds threshold all IGBT’s are turned off and normal operation resumes 2ms (typ) after over current condition is

removed.
