Part Number: BQ2980
Hi,
In my design I had mistakenly left out the pull-down resistor on the CTR pin when connecting it to my MCU GPIO.
When trying to turn on the device it is put in some strange state where it seems that the microcontroller cannot…
Part Number: BQ2980 Hello,
I have some issue with my BQ298015RUGR circuitry. I have connected a power supply to the connector J100 (4.2V - 1A) but I don't see anything on the output (TP103).
The pin CTR is pull down, which means that the chip shouldn…
Part Number: BQ2980 Hi, I would like to discuss ordering info for a part that has undervoltage of 3V, but is otherwise parametrically similar to BQ298009 or BQ298010.
Part Number: BQ2980 We are interested into procureement fo the BQ298010 with custom undervoltage threshold of 3.0V instead of 2.9. Can you provide specific information on how to acquire this part with the specific programmed threshold?
Best Regards…
Part Number: BQ2980 Hi Team,
I am working on a 2P1S Li-ion rechargeable battery configuration for my project, with an expected maximum continuous discharge current of 10 A.
For battery protection, I am currently considering the BQ298006RUGR. Could…

Hi team,
I am currently in need of battery protection for 1S2P config, Could anyone suggest me whether BQ298012RUGR is a good option for intrinsic safety. Also, i was planning for a series fuse with both the battery cells.
Please…
Part Number: BQ2980 Hi,
I am using this chip in a design where, in testing, I had found out that charging is not possible without the rest of the circuitry powered.
This is a big problem since during POR the protection chip requires Vpack to be pulled…
Part Number: BQ2980 Hello,
We are currently using a LiFePO₄ battery pack in a 1S2P configuration (one series cell group with two cells connected in parallel) in our design.
We are looking for a battery protection IC that can provide the following…
Part Number: BQ2980 Hi Team,
Posting on behalf of our customer.
I've shared this E2E post to our customer so he can reply when needed.
I'm currently looking at BQ298xx series and I can't find the specific values needed for my design. The datasheet…
Part Number: BQ2980 When the load current reaches around 250 mA , the circuit turns OFF and then automatically turns ON again. This ON/OFF cycle continues repeatedly.
This issue occurs only when the device is powered by the battery alone. When the charger…
