• RE: LTC1760, Smart Battery Selector

    Hi Till,

    The LTC1760 is indeed very old and wise, but it is still very much an active part with no suitable replacement. As a result, we have no plans to obsolete this part anytime soon.

    That said, if you don't need to charge the smart batteries, I…

  • RE: LTC4414 Power Priority

    Hello, My apologies - It is indeed the LTC4416 device and evaluation kit. 

    I don't understand your reference to the body diode since in the evaluation kit these are dual MOSFETS with body diodes blocking each other i.e. no reverse current should flow.…

  • RE: LTC3351 Hotswap Current limit

    It's an application with Embedded PC.

    When the input 24V rise up.

    The CPU will work and startup with large current.

    LTC3351 then supply load with the CPU and charge super cap at the same time.

    I found that different Mos may have different behavior…

  • RE: LTC4412 behaviour with CTL pin shutdown then complete power loss

    With a single MOSFET, CTL will only turn off the MOSFET channel. The inherent MOSFET body diode can still power the output if Vbatt - Vdiode > Vwall - V_Schottky. Use back-to-back MOSFETs (see Figure 4) to completely block forward current flow.

    The…

  • RE: DC512B not working

    Zack,

    I tried putting the 10K pull down on the bottom FET, but this did not fix the issue.  This was on 2 new boards from the production run.  The battery was not connected, and the ICs worked for a couple seconds, and then stopped pulsing on the tgate…

  • 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: DC1676A / LTC4359

    This can occur with LTC4359 controlling back-to-back MOSFETs. The output browns out because the LTC4359 has only a 10uA GATE pull-up causing slow turn-on and in back-to-back configuration the common source is pulled all the way to ground due to SOURCE…
