Thank you Anthony,
The ChemID was determined based on the brand of the cells we are using - the Panasonic NCR18650B which is in the list available for the gauge.
I see the "hickup" during charging - we need to research this as well since the setup…
Part Number: BQ40Z50-R2 Other Parts Discussed in Thread: BQ25710 Greetings fellow engineers,
We plan to incorporate BQ40Z50-R2 in a 3 cell battery pack design.
I would like to ask, if we built the battery pack management circuit successfully as…
Hi,
I would suggest the BQ25710/13 Buckboost Charging ICs. The BQ25710 supports SMBus communication and the BQ25713 supports I2C communication. Additionaly, you will need a PD controller IC to allow for PD charging with these devices. An example of…
Hi Chad,
1. VIN and VBus are two net labels. the 1-OHM resistor and 0.47uF Cap form a low pass filter, thus provides a "clean" voltage to the VBus.
2. Similarly, we often separate the ground into a "clean" low noise ground GND, and "noisy" PGND. They…
What about if we use a bq25710 battery charger in the power path to charge and maintain voltage on a 2 cell battery?
Is there something like the tps65217 that does dcdc for sitara power domains and led driving without battery charging,but can handle…
Hi, Prajith,
BQ25700A needs to talk to a host to set the charge voltage and charge current, etc. I am not familiar with BQ4050. I just haven't seen a solution like you mentioned. FYI. BQ25710 is a new device, which is pin-to-pin and software compatible…
Hi Jerry:
Thanks for letting me know. Do you have any other silicon on the system besides our BQ25710? I am trying to figure out the leakage current source. Under low power mode(disable HIDRV1 and VDDA), our part should not contribute any leakage current…
Hello Gabe,
the bq4050 supports JEITA, so if the charger supports gas gauge broadcasts then it can be used without an MCU. The following chargers could work with your system:
BQ24725A (traditional topology)
BQ24770 (NVDC topology)
BQ24800…
