• LTC4412 Power switching Issue

    We are using LTC4412 for power supply switching between 12V SMPS power Supply (PWR_IN)  and 7.4V Li-ion Battery Power Supply (BAT_V).The Block diagram and the schematic of the power supply and switching unit has been attached.
    When I connect the AC power…

  • LTC4412- Power supply Switching delay

    Hello ,

       We are planning to implement a power path controller using the below circuit. 

      We need to know the tome delay between the assertion of ctrl pin and the gate and stat pin outputs when the powwr supply is switched from primary to auxillary.

      We…

  • RE: LTC2943IDD#PBF Reverse production Available ?

    Hello,

    you may use a PMOS for a very basic reverse battery protection, as shown in the attached image. Depending on which PMOS you use, you may need to add a bias circuit with a zener diode and resistor to the MOSFETs gate to limit the gate-source voltage…

  • LTC4412做切换时的一些问题

    VBAT为铅酸电池电压:12.6V,VCC12V是电源适配器:输入电压为13.2V左右

    目的:当插入适配器时,适配器工作,蓄电池不工作。

    问题:

    1、CTL规格书意思是;控制MOS管的开关状态,但是组配置规格书没写的很明白;

    2、SATA 漏极开路输出引脚,是不是可以通过这组数据来判断电源有没有插入?这组直接IO口来判断电源有没有插入有没有问题?

    3、请帮忙看下,电路设计

    What I am trying to achieve is a…

  • ADP5052 BREAK DOWN

    WHEN AC ADOPTER POWER ON & OFF RAPIDLY, ADP5052 BREAK DOWN, AND MEASURE RESISTANCE OUTPUT PORT BETWEEN GND IS VERY LOWER THAN BEFORE.

    OFF COURSE ,DONT WORK CORRECTLY

    WHY?

  • LTC3225

    hii ' i am planning on using the LTC3225  and i have a question 

    on the typical application there is circuit that uses the LTC3225 with an  LTC4412

    and if i understand right the circuit : as long there is 5v on VIN then Q1 is disconnected and Q2 is connected…
