Hi team,
I have a question regarding the BQ24770's pre-charging profile. I understood the precharging current is regulated upto 384mA.
When the device is working in switching mode, what voltage does it start the precharge and when it ends precharging?
I want to know the operation conditions of pre-charge stage.
Thanks,
Jay
Hello Jay,
Here is a typical Li-ion CCCV charging profile:
The device starts in constant current mode until the battery reaches a certain voltage threashold.
When the device is working in switching mode, what voltage does it start the precharge and when it ends precharging?
This would depend on the battery voltage The battery voltage is not a constant voltage durning precharge mode
Best Regards,
Christian.
