I have a question about ADuM3223/4223 UVLO.
At the data sheet , I understood that the device is monitoring VDD2 for UVLO.
Which VDD2 are monitored by the device?
I want to know.
>If VDDA is 0V and VDDB is ON, would channel B would work or shut-down?
>If VDDB is 0V and VDDA is ON, would channel A would work or shut-down?
I want to know this because I am trying to design boot-strap circuit with these device.
I would really appreciate if you don't mind to teach me about this.
