Hi Team,

Customer is looking for a battery charger IC that support the Vin:5V~12V(QC2.0 standard) to charge the LIPO battery(4.2V*3cell=12.6V) at maximum current 2A. Please help to advise if we have any suitable device to approach this NBO business?

Thanks.

Arthur,

please check into bq2589x family which is compatible with HVDCP standard. The charge current is adjustable through I2C or by default at 2A.

Hi Ming,

Arthur,

Sorry for the confusion. You are right. bq2589x is designed to charge 1S battery only. For 1-3S battery, please check bq2417x or bq24133 family. However, it does not have HVDCP feature so external device for HVDCP handshaking is required. They can handle up to 17V input.

Arthur,

Since bq2417x can take up to 17V input so there is no issue to handle HV input. Unfortunately, We don't have a standalone device except intergrade into bq2589x family. This handshaking can also be handled by host to initiate HV output from adapter. .
