In Ti Web, Can not find about BQ9003 any information . if it is new product and not released yet? thank you
Part Number: BQ25887 Dear colleague,
In customer application, there is a special need.
When the battery pack is overcharged, the system will shut down. Then they insert the adapter, but only battery pack voltage larger than a special value, the processor…
Part Number: BQ25887 Presently we have a product that uses 2 LiPo cells in series. We designed a charger for this product that uses the BQ25887 and everything works great. However, we are now changing the initial product and might move to a single LiPo…
Part Number: BQ25887 We would like to use the bq25887 to completely discharge the cells in our system before charging. We would monitor the cell voltages and turn off the discharging when the voltage gets low enough. At this point we would re-enable t…
Part Number: BQ25887 Other Parts Discussed in Thread: , EV2400 I am designing a system that I plan to use the BQ25887 to charge a 2S battery pack (2Sx4P 4.2V batteries). I bought the BQ25887EVM to test the charger design before commiting my system circuit…
Part Number: BQ25887BQ25887 has a 16-bit ADC.However, when I tested the BQ25887EVM board, the voltage error was 18mV.
As shown below.
BQ25887 detection
Is there any way to calibrate this voltage?
Thank you very much!
Kuro-san,
Please refer to Figure 70 through Figure 80 of the datasheet. These oscilloscope shot were taken using the EVM and the inductor described.
Could you please provide the voltage rating for the 0.1uF capacitor and the 10uF capacitor you used?
