Hello!
I want to use ADUM3123 as a negative supply voltage switch. I will supply -5V to pin 5 and (-2.7..-2.2V) to pin 8. Will ADUM switch between these two voltages?
Please refer to the Undervoltage Lockout (UVLO) section on the datasheet for VDD2.
In this section is specified the minimum voltage required between VDD2 and GND2 for the part to operate.

Luca

The date is not written clearly. How do you understand this table? The difference between VDD2 and GND2 should be 3.2V or 0.5VThe Hysteresis by definition is the difference between Positive going threshold and Negative going threshold.
So, the difference between VDD2 and GND2 should be > 3.6V to not trip the UVLO protection on Grade A devices.
If you trip the UVLO protection, you need additional 0.5V to exit the UVLO error condition.
