Part Number: BQ24041 Other Parts Discussed in Thread: BQ24040 , BQ24045 I am using the BQ24041DSQT to change a single LiIon backup battery used to power the processor & memory when power is lost in order to provide time to save data and shutdown the file…
Part Number: BQ24040 Other Parts Discussed in Thread: BQ24041
I've used the BQ24041 with success on previous designs. However, I have a new board that does not charge the battery. The battery is LIP 3.7V 500mAh. I connected the battery to a different…
Other Parts Discussed in Thread: BQ24041 , BQ24040 , BQ25100 Hello!
I had a quick question I was hoping someone could assist me with. I am designing a wearable (think fitbit) for my Senior Design project and was looking at battery chargers. The battery that…
Other Parts Discussed in Thread: BQ24041 , BQ24040 Hi sir,
For BQ24041, is there any way to design for the function to stop charging when battery is full without fuel gauge chip?
Thanks.
Hope to hear from you soon.
Other Parts Discussed in Thread: BQ24041BQ24041 application will be intrinsically safe for hazardous locations, as per I.S. requirements, the battery will require a resistance in series with the Li-Ion battery (estimating 700 to 1.2ohms). Will this pose…
Part Number: BQ24040 Other Parts Discussed in Thread: BQ24041 If we use BQ24040, and the input will be 10V. But I saw the datasheet showed:
I was confused by the “30V input rating with 6.6V input overvoltage protection”. Why the voltage of overvoltage…
Part Number: BQ21040 Other Parts Discussed in Thread: BQ24041 , BQ24086 Team,
we would need a standalone charger like BQ21040, but without the safety timer - we have a limited power source and need to limit charging current down to 20-30mA, so it will…
Hi
Take a look at BQ24041 it has a higher OVP voltage setting, 7.1V.
Also the BQ24210 has options for operating with solar cells, OVP may be a problem.
Hi Bill,
I'm a colleague of Bas and we have in our current design the BQ24041 but getting into the limit of 6.5V overvoltage protection. We would like to use it with a maximum input voltage of 15V.
Of course this 15V will be with a lower current…
