• LTC4091: minimum battery voltage

    Hello everyone,

    I am designing a solar powered device from a 22V (maximum) solar panel and a 3.7V 4000mAh (1S2P) battery, but the datasheet says nothing about the battery undervoltage lockout.

    Does the LTC4091 have battery overdischarge protection? If…

  • LTC4091: What's a quiescent current value?

    Dear All,

    I didn't find LTC4091 total quiescent current value (internal current consumption from Vin to GND) for unloaded LTC4091 when Li-Ion Battery charging is disabled /pin TIMER is connected to GND/.

    How this value can be evaluated from LTC4091 spec…

  • LTC4091 is not charging when battery voltage higher than 3.6V

    I designed a circuit based on DC2558A development board, the problem is when battery voltage is higher than 3.6V, the LTC4091 seems not provide charging current.

    Thanks for any help.

  • LTC4091 Vout is out of specs when no battery is present!

    Hello,

    we designed a circuit based on LTC4091. The circuit is an almost identical clone of the DC2558A development board (that we do not have, by the way). The only difference is that the output current is set a little higher as well as frequency.

    I…

  • Battery charging and backup

    Kindly suggest me a part similar to LTC4091 which can act as backup switch and charging LI-Ion 7.4v Battery

  • 电源隔离与电池备用

    首先我希望最终的成品体积较小,并且拥有电池备用功能,芯片目前选用LTC4091。

    其次我希望电源隔离,所以我选用了LTM8067。

    我的系统后端有一个MCU(工作电流 20ma),WIFI模块(工作电流 500ma),一个传感器(工作电流 < 80ma),

    目前问题是LTM8067的输出功率是否足够LTC4091和我的系统使用,如果不够需要如何改进。

    还望指点一下,谢谢!
