Part Number:TPS2662
The behavior for negative input voltage is clearly defined. The same applies to an input voltage of 4.5V or higher.
Is there a defined behavior of the device in the range 0V < Vin < 4.5V (e.g. safely switched off)?
If an input voltage would change from the negative to the positive range, this range is passed through.
What happens then?
best regards,
