Part Number: BQ29200 Other Parts Discussed in Thread: BQ76200 Hello, I am trying to make 2s Li-Ion Battery charger with cell Balancing. I am using charger IC BQ2057wsn and for cell balancing BQ29200. 3731.SCHEMATIC1 _ PAGE1.pdf Charger is working fine…
Part Number: BQ29200 Hello, we used the BQ29200 in a 'quick fix' product that allows us to move away from prismatic to AAA cell's. Looking at the schematic that was done, I noticed an error. Our schematic has a Cin connected between pins 1 and 2 which…
Hello,
The OUT pin is just for over voltage fault detection.
Also, charge current is not what determines the balancing current. The balancing current is determined by the cell voltage. This should allow for cell balancing while charging.
BQ29200 and BQ29209…
Part Number: BQ29200 Other Parts Discussed in Thread: BQ24103 Hello, we're looking at using the BQ29200 for a new project here a work. Also, The batteries we are planning on using are 3.7V Li-Ion 800 mAh batteries. The datasheet in Section 8.3.6 mentions…
Hi Mario,
What protections you need depends on your system requirements from your industry or system architecture. Many systems will use FETs to cut off the charge or discharge when the battery is operated outside the parameters set by the battery system…
Part Number: BQ29200 Hi team,
Could you please help have a look at the schematic provided by customer?
And if there is other attention need be paid for customer?
Thanks.
Part Number: BQ29200 Other Parts Discussed in Thread: BQ2970 Hello,
I am designing Battery Management Circuit for 2 cel Li-Ion battery pack. Here are the required features for protection circuit 1)Over Charge Protection, 2)Over Discharge Protection, 3)Over…
Part Number: BQ29200 Hi,
I have a question about BQ29200 cell balancing. Could you please explain how does the cell balance circuit work?
The block diagram in the datasheet shows it will short VC1_CB to GND or VDD.
So I think the cell balancing current…
Part Number: BQ29200 Hi.
My goal here is to implement the IC in a circuit using 12V as it's charging voltage.
To my understanding of the datasheet, the IC itself does not draw any significant amount of current from whatever source.
Then, is it safe…
Part Number: BQ29200 Hi Team,
I have got some questions for BQ29200 that need your help.
1. I see the OVP is 4.35v, what will BQ29200 do if the voltage exceed 4.35v?
2. The range of cell balancing 7.6V - 8.4V, what will happen if the max voltage is…
