Functional Description
When the device is in Disabled State, the PWM turn-on commands are ignored. This means that whatever the
input signal INP is, the output stage (if not tristated) delivers a constant turn-off signal to the IGBT. Unless
otherwise stated, all other functions of the device work normally.
When the device is not in Disabled State, it is said to be in Enabled State. In this case, the PWM signal command
is processed normally (if the output stage is not tristated). Practically, the device is in Enabled State when
either Mode OPM4 or Mode OPM6 is active.
Active State corresponds to the normal operating state of the device. Practically, the device is in Active State
when Mode OPM4 is active.
Note:
When the device is in Active State, it implicates it is in Enabled state.
2.4.5.3 Operation Modes Description
Default Mode (OPM0)
Mode OPM0 is the default operating mode of the device after power up or after a reset event. In OPM0, the
device is in Disabled State.
The following exhaustive list of events bring the device in OPM0 Mode:
• Occurrence of a Reset Event.
• Bit SCTRL.CLRS set while the device was in OPM1.
Error Mode (OPM1)
Mode OPM1 is the operating mode of the device after an Event Class B.
The following exhaustive list of events bring the device in OPM1 Mode:
• Occurrence of an Event Class B.
In OPM1, when bit SCTRL.CLRS is set via the corresponding SPI command, the device shall normally jump to
OPM0. However, in case the conditions for an Event Class B are met at that moment, no state transition occurs
and the device stays in OPM1. The operation of bit SCTRL.CLRS on the secondary sticky bits works normally.
In OPM1, when a valid ENTER_CMODE command is received, the device shall normally jump to OPM2.
However, in case the conditions for an Event Class B are met at that moment, no state transition occurs and
the device stays in OPM1 for the duration of the event. The state transition to OPM2 is executed as soon as the
conditions leading to the Event Class B disappear.It shall be noted that no LMI error notification is issued.
Configuration Mode (OPM2)
Configuration Mode is the mode where the configuration of the device can be modified. When OPM2 is active,
the device is in Disabled State.
The following exhaustive list of events bring the device in Configuration Mode:
• Reception of a valid ENTER_CMODE command while Mode OPM0 or OPM1 active.
