Part Number: BQ79606A-Q1

Tool/software:

There are two package outlines in the latest datasheet of BQ79606A-Q1, i.e. PHP0048G and PHP0048N.

Could you explain what's the difference?

Do I need to distinguish them during layout designing and ordering?

Hi Xiaoling,

The main difference seems to be this value on the package outline:

PHP0048N is from 2023 and PHP0048G is from 2020. I'll align with the team and get back to you on the purpose of this value.

David

Hi Xiaoling,

We have two leadframes on this device PHP0048G and PHP0048N. one is a narrow strip LF and the other is a wide strip LF. Technically both leadframes should have identical dimensions, but for some reason one of them showed a different exposed pad dimension which is highlighted with the yellow highlight. This discrepancy has been sent to our team and will be updated to be identical.

David

Hi David,

Which device is the narrow strip LF and which is the wide one?

Is there any difference on technical performance but not only the dimension?

Do we need to distinguish the two leadframes when ordering the chip?

Xiaojing

Hi Xiaojing,

PHP0048G has been removed and PHP0048N is the correct package outline.

Hi David,

As you said that PHP0048N is from 2023 and PHP0048G is from 2020.

Did you have PCN for this change?

Is there any difference on technical performance but not only the dimension?

Hi Xiaojing,

For the BQ79606, PHP0048N and PHP0048G are identical and offer no additional technical performance over each other.
