Part Number: BQ25720 Hi Expert,
I can't found the register can disable adapter current monitoring(IADPT), only can find the EN_IBAT and PSYS_CONFIG.
Is that mean the IADPT can't disable when VBUS active?

Part Number: BQ25720 Tool/software: Hello,
BQ25720 is configured to manage a 3S battery. When no battery inserted, using a multimeter I checked that the VSYS voltage is 9.2V .
I try to read VSYS value (9.2V) with the internal ADC, but the reported value…
Thanks Tiger,
I mean, if my system want a stable system voltage all the time no matter charging or not, I may need another circuit to stablize the output system voltage from BQ25720 right?
Because I measured that the system voltage from BQ25720 may change…
Unfortunately, BQ25720 could not operate as a standalone charger, it typically interfaces with a host controller for a complete charge control. You can take a look at BQ24620.

Hi Saravanan,
We do not have a spreadsheet calculator, instead TI suggests following the reference design or EVM design as a starting point.

Part Number: BQ25720 Other Parts Discussed in Thread: EV2400 Hello, we are using BQ25720 in a system with a exchangeable 4s LiIon battery.
Now we have spurious issues with the BQ25720 disconnecting from supply, showing a SYSOVP bit set in register 0x20…
