Description of Operation
Normal Operation
During normal operation, V

through D
Fault Condition
The DESAT pin monitors the IGBT Vce voltage. When the
voltage on the DESAT pin exceeds 6.5 V while the IGBT
is on, VOUT is slowly brought low in order to “softly”
turn-off the IGBT and prevent large di/dt induced
voltages. Also

Automatic Reset after
Figure 34. Fault Timing diagramactivated is an internal
feedback channel which brings the FAULT output low for
the purpose of notifying the micro-controller of the fault
condition.
Fault Reset
Once fault is detected, the output will be soft-shut down
to low. All input LED signals will be ignored during
the fault period to allow the driver to completely soft
shut-down the IGBT. For ACPL-330J, the driver will auto-
matically reset the FAULT pin after a fixed mute time of
25Ps (typical). See Figure 34.
