Tool/software:

hi Support,

I have a project, when using BQ25170J:

1. at 0 deg C, the IC function correctly.

2. at 55 degC , it CANNOT cut off but only cut off at 70 degC.

When I replaced it with BQ25176J:

1. it works at both 0 and 55 deg C. 

Any advice? 

Best Regards,

Felix

    Hi Felix

    The BQ25170J and BQ25176J have the same TS (NTC) specifications and should have similar behavior.  

    Some additional information that would help:

    1.) Can you send a copy of the schematic?

    2.) What NTC is used for this test, is it part of the battery pack?
