Hi,
For this Battery Freshness Seal feature in TPS3619, can it be activated for multiple times or just only once ?
Is there any further info or application circuit available to implement this feature ?
Thanks.
CM.

Hi CM,
Please see the Battery Freshness Seal section of the datasheet on page 10 of the datasheet. It describes how to enable the freshness seal mode and how to disable it. Redoing the sequence should enable the freshness seal mode again.

HI Darwin,
Thanks. I just wonder if there is any further info or application notes. As the 5ms - 35ms windows on Vdd may post a challenge on the tester.
BTW, is there any other part with this feaure as well ?

Hi CM,
Devices with BFS are : TPS3600, TPS3606, TPS3610, TPS3617 & TPS3619. Note, the TPS3600 and TPS3610 does not have timing requirements to enter BFS mode.
