Tool/software:
BQ24650 sets the charging current to 4A, MTTP voltage to 18V, and float charging voltage to 14.5V. After charging for a period of time, the STAT1 indicator light flashes once every second. The specification sheet does not specify the flashing status. At this time, the voltage of the lead-acid battery jumps from 13.3V to 14.2V, with a charging voltage of 24V and no charging current. Excuse me, what does the flashing indicator light of STAT1 indicate?

When the battery leaves the charging circuit, the voltage measured is 13.71V. Is it caused by BQ24650 conducting battery insertion testing?
Hello Chao,
I'm a little consfused on your schematic, do you have a system load?

Hello Chao,
This part is not meant to be used with a system load.
Do you see this issue if you remove the load?

I am connected to a lead-acid battery, which then supplies power to the load through a diode。
I guess it's because the charging current (which I actually measured dropped to 400mA) has dropped to 1/10 of the set constant current charging current (which I set to 4A), starting a new round of charging. However, since the battery is almost fully charged, it has entered recharge again and kept repeating, causing the LED light to flash?
