    Hi
    

    I'm a DFAE in Japan. Our customer is looking for Charger controller Vin=4.5V to 15V, VBAT=1.8V to 2.8V and Icharge=12A to 15A.
    

    Charge by CC mode (e.g.12A) to reach VBAT=2.8V, after that charge by CV mode at smaller current.
    

    Can LTC4015 meet the charge spec ? Otherwise could you recommend another IC ?
    

    Regards,
    

    Hiroyuki
