可以用LTC3108 3.5mA输出电流为手机充电吗？

嗨，
虽然我没有您手机的规格，但这不太可能会为您的手机充电。



以下为原文

        Hi,
While I don’t have the specifications of your cell phone , it is unlikely that this will charge your phone with that amount of current.

如果电池容量为1800mAh ......我是否需要LTC3108输出的外部电源管理电路，即5V和3.5mA



以下为原文

        if battery capacity is 1800mAh…do i need external power management circuitry from the output of LTC3108 which is 5V and 3.5mA

这里有几个问题。
第一种是可以防止过度充电的充电管理电路。
这应该内置在您的手机中。
问题是手机所需的输入电压和电流是多少。
第二个是用3.5mA电量为1800mAh电池充电所需的时间，只要从芯片到电池本身的传输没有损失。
大多数手机充电器工作在5V 500mA或更高的电路上。

There are a couple of issues here. The first is a charge management circuit that would prevent overcharging. This should be built into your cell phone. The question is what is the input voltage and current required by your cell phone.
The second is the time it takes to charge a 1800mAh battery with a 3.5mA charge providing there are no losses in the transfer from the chip to the battery itself. Most cell phone chargers operate on a 5V 500mA or higher circuits.

如果我的LTC3108的输入源为500mV，我将电压提升到5V，P = VI，P = 5V3.5mA，这是17.5 mW，这个功率不足以给手机充电......

        if my input source to LTC3108 is 500mV and i am boosting the voltage to 5V , P=VI, P= 5V3.5mA which is 17.5 mW and this power is not sufficient to charge a mobile phone…
