TPS25982: Auto retry behaviour not consistent with datasheet

Part Number: TPS25982


I'm testing the TPS259827O and I've configured the autoretry pins as following:

- RETRY_DLY open

- NRETRY open

As the datasheet specifies, I'm expecting the device to retry 4 times with minimum delay during an over current response, than latch-off.

Instead the device seems to be retrying indefinetly. When connecting a capacitor on the RETRY_DLY pin, the behaviour is as expected (4 retry attempts with finite delay).

The image shows the output behaviour with Vin=15V, Rload=10ohm, R_ILIM=1600ohm, NRETRY open, RETRY_DLY open.

Do you have any suggestion?
