Part Number: BQ25303J Other Parts Discussed in Thread: BQ24105-Q1 Hi,
I'm using BQ25303J as battery charger in my design. But this part is not an automotive grade and operating Temp range in blw -40 to 85 degree Celsius.
Could you please suggest the…
Part Number: BQ25303J Tool/software: Dear Technical Service,
I followed the recommnedations from one of your colleagues about the BQ25303 and I designed this circuit:
Now what I got is that if I have D1 placed I see a significant voltage drop…
Part Number: BQ25303J Hi,
I am currently using the BQ25303J to charge a 5000mAh Lithium Ion Cell (21700). I have set the VBAT Reg at 4.2 V by connecting VSET Pin to ground using a 0 Ohm Jumper. The battery should charge should 4.2V, but
the charger…
Part Number: BQ25303J Tool/software: I'm stuck trying to calculate the thermistor resistors.
It seems to me that the equations for setting the resistors are wrong.
I get a negative number for R2
I gather there is no excel spreadsheet for this part…
