• LT1512 high current consumption

    Good afternoon,

    One of our circuits is based on the LT1512 and it is used to charge a 8.4V NiMH battery at 500mA maximum current.

    LT1512 is managed by a microcontroller and input voltage comes from a solar panel. Once voltage is detected at the input…

  • LT1512 - From 200mA to 20 mA without any reason

    Hello

    I took the LT1512 figure from the spec as attached. The battery is a 8,4V NimH 2000 mAH.

    The current value is limited by R3 that is in my case 0.5 Ohm so the charging current is 200 mA.
    R1 was defined further the spec formula, means 71k for R2 of…

  • LT1512 slow charging

    Hi, I'm developing dual power source device. 1st source is 12.4V adapter, the 2nd is 12v DELTA battery. PowerPath Controller is LTC4418. So the problem is that power consumption of LT1512 from supply more than 200mA and only 5mA goes to battery. Current…

  • RE: using LT1512 for charging 4 batteries in series

    The LT1512 includes both battery-voltage and charge-current sensing.  (FB, IFB pins).  The battery is charged at constant current until the FB pin voltage reaches 1.245V.  As long as the battery is connected and input power is present, the LT1512 will add…

  • Question about LT1512

    Hi

     

    I have two questions about LT1512. Please take care of this case.

    1) What is the shut down voltage to disable LT1512? Is it 1.3V typ written in the data sheet?

    2) How does LT1512 work when removing a battery while it is being charged? The LT1512 works…

  • LT1510/LT1511/LT1512 Battery charger IC

    1. Can we create a PV based battery charger using LT1510/LT1511/LT1513? The input voltage will be connected to a PV panel of appropriate spec. Is there any additional thing to be taken cared of?

    LT1510 is a current mode PWM step- down switcher where the…

  • RE: Help for design of a battery management system

    Thanks for the detailed response.  For simplicity now, I think I'll nix the option of charging another device, as well as running on the USB power.  I want to focus on the basic function of charging and monitoring a Li-Ion battery.  Two Li-Ion batteries…
