Hi Pero,
A "multi-cell" charger has the capability to charge multiple cells. We have chargers that also perform integrated cell balancing but these are explicitly mentioned (example: BQ25887). This charger has protection for overcurrent and overvoltage…
Hi Satoshi,
Sorry for the delayed response, for some reason the BQ2000 tag did not appear. For other posts if you mention part number when creating the post we will have a much faster response time!
You are correct that most charger IC does not have…
Hi Cherry,
Can you provide the resistance of the Ilim pin and the Ichg pin when there is no input voltage? The max charge current allowed is 2.2A if Ilim >= 2.2A. If Ilim < 2.2A, the highest value of Ichg is Ilim.
In addition, we require placing a…
Other Parts Discussed in Thread: BQ25882 , BQ25883 , BQ25886 , BQ25887 , BQ24773 , BQ25713 Asking for the recommendation on the NVDC charger
Hi Team,
Customer is looking NVDC charger.
Would you please recommend the proper solution based on…
Part Number: BQ27520-G4 Dear colleague,
Our customer is using BQ27520-Q1, here is a strange issue.
This customer using the processor to communicate with BQ27520.
But when the processor restart, the processor can't communicate with BQ27520, and this…
Hello,
You can see our BQ2588x Schematic Checklist for schematic and layout tips. Based on your provided schematics, I would recommend additional capacitance at the PMID pin, and placing the capacitance as close as possible to the IC.
Please let me…
Hi Mickey,
Here are my comments on the BQ25883 schematic.
The absolute maximum sink current for the STAT pin is 6 mA, as shown in Section 7.1 in the datasheet. I don't know the forward voltage drop for your white LED (LED1001), but I suspect that…
Hi Enrico,
The thermal pad on the back of the IC must be soldered to GND. Please refer to the layout guidelines in Section 11 of the datasheet.
Please also follow the schematic checklist document below. For the PMID capacitance, at least 10…
Hi,
1) R16130 is not required. We include this resistor on the BQ25883 EVM because measuring the voltage drop across the sense resistor gives us a convenient way to calculate the system current, but you can leave this resistor out of your schematic…
Alpaslan,
I cannot offer support on the S-8252, but it seems Table 11 of their datasheet offers some functionality of the FETs. Connecting VSYS to VDD seems unnecessarily redundant. Is there a reason you made this connection?
Attached for your reference…
