Other Parts Discussed in Thread: BQ78350
Hi there,
I'm working with your driver BQ76200.
On the pdf "SLVA729A–November 2015–Revised February 2016 " you can see two topologies:
- 4.1 1xCFET/1xDFET --> Precharge transistor option with the same path to charge and discharge.
- 4.3 4xCFET/4xDFET--> No precharge transistor. Separate path for charge and discharge.
I would like to know if there is a topology with both of them features, I mean: Precharge transistor and charge and discharge path independent.
I think that this option is nor feasible because according to BQ76200 datasheet the the PREcharge voltage ON is : "V V(PACK) > 17 V, V(BAT) < V(PACK), V(PACK) – (PCHG)" so the reference is "Vpack+". And the PACK+ pin in a precharge mode could be unknown just because they are different path.
What do you think? I'm right?
There is some option to CHG and DSG path independent; and a PRE-charge transistor, all together?
thanks a lot
