Part Number: BQ25820 Tool/software: Hi,
Can you please explain the usage and the difference of the:
FORCE_BATFET_O FF ( REG0x19_Power_Path_and_Reverse_Mode_Control Register)
and the EN_BATFET_IDEAL _DIODE
and the relation between both
In general and in…
Part Number: BQ25820 Tool/software: Hello,
I know the BQ25820 is limited to 20A in the datasheet. What would prevent using it at 30A with higher current external FET's and high current Inductors?
There is a note about the Rsense remaining 5mOhms…
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).

Hello Leif,
The charger should work with the battery gauge, the main thing that the battery gauge cares about is the current going in and out of the cell meaning it is versatile with many loads and chargers.
Thank you, Alan
Part Number: BQ25820 Tool/software: Hi, what is the meaning of HIZ mode? With HIZ enabled, the device disconnects the input source and will provide the system with battery power.

Hello Vincent,
Vincent Xu said: Mostly, based on the spec of BQ25820,
we don't have a spec for the vsys rise time after VAC falls below ACUV. However I measured using our EVM, and the rise time was less than 1ms.
Can you confirm you followed the schematic…
