• LTC4353

    Hi,

    We designed a little circuit to select between 2 voltage source with the LTC4353 but we don't have the result expected.

    We want to be able to shutdown Vout and select Vin2 if present instead of Vin1(always present) but Vin1>Vin2

    Vin1 = 7.4V…

  • LTC4353问题

    我在使用LTC4353过程中发现电源切换过程中有周期性跌落现象,不知道和什么因素有关。

    下图是我当前的电路,当3.6V18650电池在给负载(200mA)进行供电时,插入另一个4V电源,经常出现电源周期性跌落现象。

    跌落周期5.634ms。

    而且,从3.6V到4V的切换过程中,会出现20us左右的跌落,这和规格书中ton的时间(0.4us)相差的比较多?

  • LTC4353 secondary input voltage drop

    I'm experiencing a strange behaviour on a board where I'm using LTC4353 as a "12V Main and Auxiliary Supply Diode-OR" . The circuit I'm working on is depicted below (it's pretty the same circuit found on page 11 of the original datasheet…

  • LTC4353 Permits reverse current

    Hello,

    We are using a circuit where it gets Power from two supplies and have implemented LTC4353 for reverse current protection. Such that one of the Source(Battery) does not get loaded.

    We found issues that the mosfet M1 and M2 ( We used different…

  • LTC4353 back-to-back mosfet

    Hi all,

    I was wondering if LTC4353, that seems to be the doubled version of LTC4352, accept back-to-back connection for the external mosfet.

    Is it possible?

    The datasheet do not mention this possibility, but this is available in the little brother LTC4352…

  • LTC4353 OR-ing diode enabling below 0.8V not 0.6V

    Hello,

    I am using the LTC4353 in the configuration shown in the attached image. My application requires that the AUX voltage be higher initially than the MAIN voltage so I would like to disable the AUX current path until the main voltage drops below 9V…

  • RE: Need ideal diode controller for high current

    Hello, An N-channel controller is more suitable for your current level. These are in the LTC435x series: consider LTC4353 (dual 0V-18V), LTC4355 (dual 9V-80V), LTC4359 (single 4V-80V with switch capability), or select "N-Channel" under Ideal Diode column…

  • 关于ltc4372的turn-on时间

    我看到像之前的一些老料比如LTC4353都有ton(gate)这个参数,但是ltc4372的规格书中的ton参数是指的从SHDN到输出的延时。请问下ltc4372对应的ton(gate)时间是多少us?
