Hi,
First of all, I have been checking the forums for similar issues, especially on the bq24630 but don't think they are completely similar to my case.
We have been designing chargers…
Dear Tim,
You can try to replace the inductor, but I do not think that will solve the issue. If you choose to decrease the inductor, you will need to abide by the frequency requirement in Section 9.2.2.6 of the datasheet by changing the output capacitance…

The customer is looking for a kind of device which can meet below requirements:
1. supports charging of the following Li-Ion battery packs: 4-series 18650-sized Li…
Part Number: BQ24600 Other Parts Discussed in Thread: BQ24620 , BQ24630 Hello,
I have a customer who is looking into using BQ24600RVAT to charge LiFePO4 battery chemistry. I have checked the datasheet and they only mention about Li-Ion/Li-Polymer battery…
Part Number: BQ24618 Hello everyone and good afternoon,
I am using the BQ24618 in one of my designs to charge a 6-cell Li-Ion Battery, but I am experiencing some problems with it.
The input/system side of the design seems to work fine. When I connect power…
Part Number: BQ24618 Hello,
I working on 3s li-ion charger. I have build circuit of bq24618 ic as per given in the datasheet. bq24618 works well but without BATFET mosfet. If i used BATFET mosfet high current flow through it and dameged Q4 ,Q6 MOSFET…

My customer survey standalone charger solution. I think BQ24618 is okay to them but I would like to know whether we have better solution for supply concern…
Part Number: BQ24618 Other Parts Discussed in Thread: BQ24600 Hi Team,
There is a good new that we could DIN TI product!
The new project requirements are as follows:
Vin : 24V~30V
Vo : 24V
Io : 2.2A
Less pin IC
