BQ25892: Design Review

Ashwati Krishnan
Intellectual 520 points
Part Number: BQ25892

Hello there, 

I am attaching our schematic for the BQ25892 battery charger. I would appreciate a review to ensure that the following functionality can be achieved with this hardware configuration:

  1. The device needs to charge when the USB is connected, otherwise it will run on battery. It does not need to charge another device.
  2. We want to be able to read the charging status and the battery capacity through the I2C.
  3. The current limit that we have designed for is 2A.
  4. Are the data on the STAT pin and the PG pin available in registers that can be accessed through I2C?

Are there any points I should pay attention to before sending these for manufacture?

Thanks!

Ashwati
