• RE: LTC4416 Reverse Polarity Protection

    Per page 2 of the LTC4416 datasheet, V1/V2 absolute maximum rating goes down to -14V, i.e., they can tolerate -12V without damage. Ex/Hx pin absolute maximum only goes down to -0.3V but their pin current is limited by the external divider resistors. It…

  • RE: Help with the LTC4416-1 design

    1) The LTC4416-1 can drive high current mosfet rated of over 50A?

    Since the currents are getting high, you should look into the LTC4421, since it uses N-channel FETs (lower RDS(ON)).

    2) Can the LTC4416-1 be set in a way that if the…
  • LTC4416 Power ORing

    Hi,

    I am doing a project of dual power input and single output, with max load current 30A. The 1st input is 24V from ACDC supply, and 2nd input is battery with voltage around 23V to 28V.

    In our case, fixed DC input has higher priority, when DC input is…

  • LTC4416 failure mode

    Hi,

    From the datasheet of LTC4416, there is no max current limit at absolute maximum ratings table.

    So what will happen if internal IC is short circuit?

    Is there any possibility of this IC failure that casing V1/V2/VS current over loading?

    The switchover…

  • LTC4416 - Recommendation for Switchover circuit

    Hello:

    I am interested in using the LTC4416 for power OR-ing our device which must meet a special case. I wanted to ask Analog for directions on how to use the LTC4416  for this case (although we are open to other suggestions).

    We have an UPS that outputs…

  • LTC4416 oring controller gate driver current

    Hello

    I need an ideal diode controller for my new electronic circuit product. Before, I have used LTC4416 controller and FDD9510L-F085 Mosfet for ideal diode application but with current through Mosfet only about 10A. In new circuit, current through Mosfet…

  • Can LTC4416 support hot-swapping batteries?

    Hello, we want to power a load from two 14.4V lithium-ion battery packs where either can be disconnected at any time and the load will continue getting power. It seems the best way to do this is to build our circuit like shows in Figure 4 of the datasheet…

  • RE: Is it possible to switch the power supply when LTC4416 V1 and V2 have the same voltage?

    Hi Naohisa,  1. Use the enable pins (E1, E2) to switch off the channel you don't want to use. 2. Looks like V1 is not decaying for some reason (maybe it is being pulled up by V2/Vs). Try increasing the V1/V2 bypass capacitors (or increasing bypass/load…

  • 关于LTC4416主备电源使能切换问题

    Hello 

    请教一个问题,如下:

    有一个负载设备需要12V/10A供电,第一输入主电源来自AC/DC模块输出的12V,第二输入电源来自备用4S1P铁锂电池(12V/5Ah ),电压最大14.6V。

    #1、设备处于关机状态时,主电源不上电,铁锂备用电池不为负载供电开机。

    #2、设备处于开机工作状态,主电源丢失异常,铁锂备用电池将无缝接的为负载供电,保证设备处于开机工作状态。

    #3、设备处于关机或开机状态,主电源上电,铁锂备用电池都不为负载供电。

    针对#1,是否可以设置E1 < Vref,E2# >…

  • RE: Separate high-side MOFET drivers with outputs tied together in cable.

    Hi,

    You may want to  check the following IC.

    1. LTC4416 (36V, Low Loss Dual PowerPath Controllers for Large PFETs)
    2. LTC4364 (Surge Stopper with Ideal Diode)

    Both have examples in the Datasheet on how to implement Redundant/Load Sharing.

    LTC4416 does not…
