Part Number: BQ25756
Hi everyone!
I would greatly appreciate a schematic review from TI experts for the BQ25756 IC.
My design goal is ;
About 4.8V to 48V input
6A input currrent
4A Battery Charge current
1S Li Ion battery (4.2V max charge…
Part Number: BQ25756 Other Parts Discussed in Thread: LMG2100R044 , Hi,
I've been successfully using the BQ25756 in multiple MPPT designs. I have a new MPPT project that requires high power density. I wanted to check if I could use the BQ25756 mosfet…
Part Number: BQ25756 Hello,
I am working on a charger design that will be used to charge lithium batteries in both a 4S (16.8V) and 2S (8.4V) configuration.This voltage shift is too large to handle by adjusting the internal VRef via the I2C interface…
Part Number: BQ25756 Other Parts Discussed in Thread: PMP41115 Hello,
We have used BQ25756 in our battery charging applications and have had great success. Now we would like to charge higher voltage batteries aswell, but the issue is with BQ25756 max…
Part Number: BQ25756 During testing, we observed that after the power input is re-applied, the BQ25756 does not resume charging unless we re-configure the charge current setting . Is this the expected behavior, or are we missing a configuration related…
Part Number: BQ25756 Other Parts Discussed in Thread: BQ25758 Hi,
I have a question about BQ25756 aplication. In our case we don't need boost opiton (we use only buck). So my question is if we could not suit the lowers mosfet's to reduce spaces on the…
Part Number: BQ25756 Hello,
I am designing a battery charging circuit using the BQ25756 integrated circuit and plan to power the system with a solar panel operating in MPPT mode. In TI's reference design (as shown in the schematic I attached), there…
Part Number: BQ25756 Hi team,
I've designed a BQ25756 charger for a 4S LifePO4 battery ( Battery_Charger_Schematic.pdf ).
The design parameters were:
Battery charge voltage=14.6V. The battery indicates a charge voltage recommendation of 14.4-14…
