BQ24800: Charging profile

Hello Ishiwata,

Does BQ24800 have a Li-ion charging profile?

The bq24800 charges Li-ion battery in constant current (CC), and constant voltage (CV) mode. The host programs battery voltage in REG0x15(). According to battery voltage, the host programs appropriate charge current in REG0x14(). When battery is full or battery is not in good condition to charge, host terminates charge by setting REG0x12[0] to 1, or setting either ChargeVoltage() or ChargeCurrent() to zero.

Shuji Ishiwata said:

Also, are charging profiles provided when controlling with an external microcontroller?

The charging profile should be the same when controlling with an external microcontroller, as long as the the charge current and charge voltage are set correctly.

Here is a thread on how to access the BQ24800 full data sheet:datasheet

Hello Shuji,

The BQ24800 does not have battery pack temperature monitoring function. You will need an gauge or monitoring device to monitor battery pack temperature.
