Li-Ion battery charger

[Nicmus]

Hi all,

Just wandering if anyone came across a single cell (3.7V), Li-Ion, minimum 1A, self contained battery charger for vehicular (cigarette lighter) usage.
Any input,links or advise will be appreciated.

Thanks in advance,

Nick

What do you mean by self contained?

[Nicmus]

Sorry if I wasn’t clear.
I mean all the charging smarts should be in this piece, not just a 12V to 5V converter.

I think Maxim has some ICs dedicated to Li Ion charging

Thanks Jerson,
I'm looking for something allready built.
You are right Maxim and Linear Technology have a large selection of charging controller chips.
I do not have the time to build and manufacture my own so I must find a source.

Sparkfun!! Sparkfun!! Here is a 5-12V charger and a 3.7-7V charger. They have a lot of useful little things like this.

Thank you Tim!

The first link is exactly what I need.
I did search Sparkfun but found only the second option which does not meet the current requirement (minimum 1A).

Thanks again,

Nick
