Part Number: BQ25638 Tool/software: All,
I'm working on a design based on the BQ25638 charger. In order to keep the cost low I'm trying to avoid any via in pad PCB process. This naturally forces some restrictions on access to various pins. It…
Part Number: BQ25638 Tool/software: Hello, We're employing this part in a new design and although on page 31 it says that VBUS is the OTG output, in the block diagram the VPMID pin also connects to the boosted voltage. I just need 100% clarification…
Hi Shuvam,
Part No: BQ25638
I am currently working with the BQ25638 battery charger IC and need to calculate the battery voltage (VBAT) and battery current (IBAT) from the ADC readings. Could you please provide the appropriate formulas for these calculations…
Part Number: BQ25638 Tool/software: Hi there, Is there a C-language MCU driver available for the BQ25638? If not, can you provide a driver for a similar I2C-based buck charger?
Thanks! Mark
Part Number: BQ25638 Other Parts Discussed in Thread: , BQ24250 Tool/software: Hi Team,
Could you help to provide charger IC comparison table for selection between BQ24250 and BQ25638/BQ25638D? Thanks!
Part Number: BQ25638
Hi,
I am trying to source a li-ion charger ic that meets the following specs:
1 cell min (4.2V)
20V input
>4A charge current
i2c
It would ideally have power path management without needing external ics, but this is not a must…
Part Number: TPS25751 Other Parts Discussed in Thread: BQ25638 , Tool/software: Hi,
we want to use the TPS25751D PD Controller and the BQ25638 Battery Charger for a Battery Device with USB-C PD for Battery charging and with OTG support to drive external…
Part Number: BQ25638 Tool/software: We have some quick questions:
For BQ25638, the spec for ICHG is 80mA minimum. What will happen below 80mA?
Is it just lower accuracy for charge current regulation?
What is the minimum value for input current, below…
Part Number: BQ25638 Other Parts Discussed in Thread: BQ25620 Tool/software: Hi team,
Could BQ25638 support ship mode like BQ25620, I haven't found the description in BQ25638 datasheet.
Could you please help to check this out？
Thank you,
Yishan …
Part Number: BQ25638 Other Parts Discussed in Thread: BQSTUDIO Tool/software: Battery charger team,
What formula should be used to convert the ADC reading to a temperature value? I didn't see this in the datasheet. The register is TS_ADC.
I found…
