TPS2662: Behavior between 0V < Vin <4.5V

Wilfried Hermann1

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,

Hello Wilfried,

We are looking into this and will get back in couple of days.

Hello Wilfried,

Between 0V and V_(PORR)[=3.73V typical]_,the device keeps the internal MOSFETs off . The device checks other inputs like UVLO, ILIM, Junction temperature at POR and turns ON the internal FETs or keeps the internal FETs OFF based on these inputs.
