BQ24160: default setting

Julia Prigara
Prodigy 60 points
Part Number: BQ24160

Hi, 

What will be the USB input current setting of BQ24160 if:

1) The charger starts from an external DC adapter

2) The charger starts from USB, but without an active device at D+/D-

3) The charger start from USB, but there is already an active device at D+/D-, which does not support BC1.2.

4) The charger starts from an external adapter, but then a valid voltage is applied at USB and the adapter is disconnected.

Best regards, Julia

    Hi Julia,

    Regarding 1, if connected at IN, default input current limit is 2.5A per datasheet.  

    Regarding 2 and 3, if not detected, default input current limit is 100mA.

    Regarding 4, if SDP was detected, then 100mA.  If CDP/DCP was detected then 1.5A.

    Regards,

    Jeff
