Other Parts Discussed in Thread: BQ25792

We want to design a charging base to charge two game handles at the same time

The specific requirements are as follows:

1. Input voltage: it can be VBUS or AC adapter

2. The output interface is type-c

3. The maximum charging current of each handle is 1.4A

4. Charging status indication (charging, charging completed, charging fault)

5. The charging current can be regulated independently as far as possible (trickle charging / pre charging / constant current charging / constant voltage charging, and the voltage and current limits can be set independently)

5. Charging protection function (overcharge / overtemperature / OCP, etc.)

Is there a suitable IC to recommend? Is there a reference line to provide? Thank you

    Hi,

    I have a few questions:

    Are you looking you one charge IC to charge both handles at the same time at 1.4A or one charger IC for each handle?

    What is the maximum input voltage for "VBUS or AC adapter"?

    Do the handles have 1S LIIon batteries?

    Do you want a standalone (no I2C/SMBus) or host controlled (I2C/SMBUS) IC?

    Regards,

    Jeff

    Dear Jeff:

       The answers to your questions are as follows:

      

    Are you looking you one charge IC to charge both handles at the same time at 1.4A or one charger IC for each handle?

    answer：If there is a charging IC, it is best to charge two handles at the same time. If not, only one charging IC can charge one handle, just put it in a charging base

                   Two aspects can help recommend.

    What is the maximum input voltage for "VBUS or AC adapter"?

    answer：VBUS can be type-C, AC adapter output 0 ~ 18V

    Do the handles have 1S LIIon batteries?

    answer：Yes，Each handle has one battery, and each battery has only one cell

    Do you want a standalone (no I2C/SMBus) or host controlled (I2C/SMBUS) IC?

    answer：No request, everything is OK

    Thank you！

    Hi,

    BQ25792 is a buck-boost charger capable of input voltages up to 20V.  It is a host controlled charger, meaning for full configurability, you would need a host processor/microcontroller plus software to operate the charger.  It will operating in default mode with limited functionality.
