Part Number: BQ79616-Q1
Other Parts Discussed in Thread: UCC28782, BQ79616

Hello:

We need to develop complete power systems for portable medical equipment for a customer. It will have a root converter using UCC28782 as ac-dc front end set to 26V @100W max. It will have a WT6636F chip to interface with USB C PD receptacle

It is going to charge a portable lightweight battery yet needs 480 Whr at 24V pack.

Do we need to implement a full battery management system for this application? Will that be optimum with BQ79616 chip?

Do we then program it using a GUI or full-fledged "BMS Studio"( as in code-composer-studio) or something of this sort?

Appreciate any reviews on this matter.

Hi Robin,

How many cells is the pack? Typically bq79616 is suited for higher voltage packs and requiring advanced safety and performance features in automotive for example.

Regards,

Taylor

Taylor;

Ok, got it.

We only design for higher power/high voltage systems. So we might have to get familiar with the BMS. Not too keen on using embedded ones with cheap LiPO one finds in ALi like they were growing as bok-choy...

Ok well if you end up using it, you can request access to our mySecure folder on the product folder for more resources such as our GUI/EVM/example code in CCS. Please open up a new thread if new questions arise.
