Other Parts Discussed in Thread: BQ51222

Hello,

              Customer use BQ51222  and USB connector two power source. Two power source (BQ51222/USB connector) both input to a charger to charge battery. The output charge current is 250mA for BQ51222 and USB connector and need I2C configuration.  They also request non-Q1 and Q1 charger solution to meet above requirement. Do we have suitable solutions? Thank you.

    Hi Patrick
    Does the charger have two inputs? One for wireless power and one for USB?
    If this is the case then Q1 is not needed and /AD-EN will be open. But AD should be connected to USB input as a way to turn off wireless power when USB is present.
