BQ51222: Charging status register and I2C format

Patrick Chen

Part Number: BQ51222

Hello

Which register we can read via I2C to monitor charging status to battery ex: monitor charging is continued... ?

Do we have complete I2C read/write timing diagram and command format of BQ51222 due to not clear on datasheet? Thank you.

Hello
The BQ51222 I2C Register Maps are available in section 8.5 of the data sheet.
Device is a power supply that will power a system or battery charger and battery charging status is not available.

Hello Johns

Sorry, could I know which register or bit can indicate charging is active or suspend? And Has any I2C command protocol to let customer configure via I2C? Thank you.
