Hello,
In our design, we have a 28V power on VDRAIN and a 15V power on VM.
The 15V power is always there but the 28V power can dissapear.
We did that in order to keep the driver configuration even in case of 28V power loss, which is a nice addition to the component compared to previous generations.
However, from my understanding of the datasheet, it seems that even for the configuration of the component, the ENABLE pin must be activated (despite being flagged as GATE driver enable).
Do you confirm ?
Does the VDRAIN power need to be present too in order to configure the component ?
In case of loss of the VRAIN power, do you confirm the configuration is kept ?
In case of deactivation of the ENABLE, do you confirm the configuration is kept ?
Best regards,
Clément
