• LT3652HV charging issue

    Hi,

    We would like to apply LT3652HV (DC1568A reference board) to charge 4.2V Li-ion battery.

    Modify the resistor value (Rfb1=91K, Rfb2=332K, Rfb3=178K) and setting floating voltage at 4.2V.

    However, we find the CHRG LED is blinking when Vbat reach floating…

  • LT3652HV Charging Issue

    I am using LT3652HV for charging the SLA battery (12V). I have followed the circuit diagram of DC1688A EVB kit to avoid any kind of error. But the charging is not happening. For testing the circuit, i have connected a 12V SLA battery at BAT pin of LT3652HV…

  • RE: Inquire of cell# limitation of LTC4010

    Hello,

    16 is the max number of cells for the LTC4010. We do not have a dedicated NiCd charger that can do 20 cells.

    We do have some generic chargers that will work such as the LT3652HV, but note that these do not have termination that is recommended for…

  • RE: LTC4120 not enough current

    Hi Ricardo, 

    Yes you are right that LTC4120 provides up to 400mA of charge current. To get more charge current, you can use LT3652HV as the receiver IC. Please refer to this link below for the reference of this design:

  • RE: LTC1731-8.X in series from one power supply

    Yes you are right, a balancer is needed and I think those are all great suggestions. I will have to implement an active op amp balancer like you said.

    My options for a power supply are very fluid, with the limitation that I want one supply to plug into…

  • Power Regulator for solar charge of low power application

    I have a device which has a 9.6v (9v form factor) LIFEPO4 battery.

    The device draws 100mA at peak power but most of the time it sits at less than 1mA.

    I'd like to add a solar panel to augment the battery life, now, with a 320mA battery, I have around…

  • LTC4125 - Burst of Power

    Hi everyone,

    I have somes problems with the LTC4125. I'm using this component as a TX to do a power transmitter to charge a single cell LIFEPO4 with the help of the LT3652HV as a RX.

    I found this schematic on the page 26 of the LTC4125 datasheet.

  • LT3652 3.3V float voltage

    Hi,

    If i want the float voltage of the LT3652 to be set to 3.3V - do I leave the Vfb pin floating? 

    All of the datasheet notes are about setting this level to something higher than 3.3V but do not mention if you want to leave it as 3.3V.

    Many thanks

  • LT3652 & SEPIC

    Hi - I have a design with the LT3652, it's a very good chip. I'd like to know if there is chance that it could be used in a SEPIC topology? I use it as a 3-LiIon charger (1A), but my Vcc can be from 10 to 20V. So currently, I have a LT1935 to do…
