Description of Operation
Normal Operation
During normal operation, V
trolled by input LED current IF (pins 5, 6, 7 and 8), with
the IGBT collector-to-emitter voltage being monitored
through DDESAT. The FAULT output is high. See Figure 37.
Fault Condition
The DESAT pin monitors the IGBT V
voltage on the DESAT pin exceeds 6.5 V while the IGBT is
on, V
the IGBT and prevent large di/dt induced voltages. Also
activated is an internal feedback channel which brings
the FAULT output low for the purpose of notifying the
micro-controller of the fault condition.

Automatic Reset after
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-333J, the driver will auto-
matically reset the FAULT pin after a fixed mute time of
25Ps (typical). See Figure 37.
