    Re: Lithium battery woes

    Shantanu,

    I used the DS3231SN # chip (40 pieces) years ago. I have not had problems. My circuit was with CR2032 directly connected. In 2007, the purchase price was 2.70. The current price can be...

    Re: 3.3v circuit from a LiPo cell

    hi,
    Another way would be to use an LDO with Power Good (LP5912-3.3DRVR), then do the bypass externally with a MOSFET through your PIC.

    Re: 3.3v circuit from a LiPo cell

    Hi,
    I think the best thing for this would be to put an LDO with bypass. When the voltage is higher than 3.6 the LDO works and when it is lower the voltage goes directly. I have not used this, but I...
