  • 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…

  • LTC4412 behaviour with CTL pin shutdown then complete power loss

    We are designing a  low voltage (Max 19VDC) lighting system that uses mains primary power and battery backup. Circuit design would follow figure 3 of the typical applications diagrams.

    One of the planned features of the system is battery monitoring and…

  • 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…
  • 关于LTC4412是否符合应用场景的求教

    在某项目中由于要使用到双路供电控制,经查LTC4412的用途似乎可以满足需求,因此特来请教:

    系统中的负载需要使用双路供电,

    一路为自带的14.8V聚合物锂电池组作为常备电源,另一路远程供电,也是14.8V聚合物锂电池(或者是在有市电的情况下使用一个16V的直流电源供电)

    负载实际工作时的电流大约是50-60A,

    请问使用该型芯片是否可以满足这样的使用场景,还有就是PMOS选型时,如果一颗不能满足电流需求,是否可以两颗并联.

    先谢谢前辈指教,还望不吝解答

  • 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

  • LTC4412 with CTL controlled by supply voltage

    Hello,

    I have a question regarding the LTC4412.

    I was wondering if it is possible to wire the IC as per figure 4 from the datasheet, but control the CTL pin simply via one of the supply voltages so that the MCU is not needed.

  • 6V外接适配器给2节镍氢电池充电与LTC4412配合,有没有推荐的芯片和电路

    6V外接适配器给2节镍氢电池充电与LTC4412配合,有没有推荐的芯片和电路?

  • RE: OV and UV protection for 18650 single cell Li-ion battery

    I'm planning to use LTC4412 as a High Side Power Switch between LTC4365-1 and the switching regulator. It'll be better if we have discussion on that in a separate thread.
