Part Number: BQ25820 Tool/software: Customer is using NiMH battery 2xC type (in series) 2.4V 5Ah.
Does the BQ25820 support for charging NiMH battery chemistry? Product details says yes, but details are difficult to find.
If it does support NiMH chemistry…
Part Number: BQ25820
Tool/software:
If power path is not needed on BQ25820, remove the BATFET, connected Pin 32 (SYS) to Pin 33(VAC), leave Pin 15 (BATDRV) floating, and connect Pin 16 (BATSRC) to Pin18(VLSNS).
Best Regards,
Christian
Part Number: BQ25820 Tool/software: Hallo
We are using the BQ25820 similar as on the EV-Kit. Which solution could you suggest to implement a soft start at the Q5 to reduce the inrush current during switch on of Q5.
Thanks

Part Number: BQ25820 Tool/software: Hi,
We have designed a PCB with a single cell LiPo battery and a BQ25820 charger and also a BQ27441 gauge IC.
The charging doesn't seem to work though. Battery is 3.0 - 4V (3.7V nominal) 3000mAh. We use +12V as…
Part Number: BQ25820 Are there any circumstances under which the ACFETs and BATFET are both turned on when using bq25820?
My use-case is fairly height constrained, so I'm trying to optimize output capacitor voltage ratings where possible...
Part Number: BQ25820 Other Parts Discussed in Thread: BQ24610 Tool/software: Hello I am considering using the BQ25820 for battery charging, but how does it differ from the BQ24610? The battery is a LiFePO4 battery module (12.8Vx2, 20000mAH). TI recommended…
Part Number: BQ25820 Other Parts Discussed in Thread: BQ25756 Tool/software: Hi, Please tell me how to determine the output voltage in the BQ25820 settings. I'm checking the settings of each register via I2C, but to determine the voltage output, should…
Part Number: BQ25820 Tool/software: Hi,
I would like to verify/ confirm the DCDC duty cycle
Our case:
