Part Number: BQ29209-Q1 Hello support team,
My customer would like to know if it is possible to change the overvoltage protection threshold (Vprotection = 4.3V) of bq29209-Q1 by trimming or other manufacturing process.
Could you please support this?

Part Number: BQ29209-Q1 Hello,
My customer is looking for secondary protection IC for 4cell battery, automotive application.
I found BQ29029-Q1, is this device stacable for 4 cell appliction?
Passive cell balancing functionality is not required.
Best…
Other Parts Discussed in Thread: BQ29209-Q1 Hi
I'm looking for a overvoltage protection circuit and balancer for 2 cells. I found bq29209-Q1 and just studied the block diagram and "typical application".
I need a output current from the 2…
Hi Mehmet,
I am covering the monitor and protector portfolio and unfortunately we do not have a monitor that can work with your 2s application.
The only offering that appears to fit best here is our BQ29200 & BQ29209 2s protector with cell balancing feature…
Hello Luis,
Luis H. S. said: Yes, you are correct. Not possible in this configuration unfortunately.
You see some problem on this configuration ?
Luis H. S. said: Couldn't you just connect an additional resistor from VUSB to Q3 directly and avoid using…
Hello Kunal,
Please see below response.
1. Actually, the CDH port is connected to the pin OUT of BQ29209-Q1. By doing this, I am isolating the battery module (denoted by BATT+) from the rest of the circuitry. Both power path will both be activated once…
Part Number: BQ29209 Other Parts Discussed in Thread: TINA-TI Hi, the recommended schematics for external cell balancing might not work like it's intended. In case of Q1, the Drain Source voltage will be the same as the Gate Source voltage when activated…
Part Number: BQ29209 Other Parts Discussed in Thread: , BQ25882 Hi,
first of all, I'm sorry for my poor experience about battery management circuits.
I have to put in series two Li-ion batteries (3,7 to 4,2) in order to get more voltage from them…
Part Number: BQ29209 Other Parts Discussed in Thread: BQ76200 Hi,
I am having trouble with the implementation of the external cell balancing circuit for the BQ29209 from the datasheet.
We are using the following values for the passive components in…
