All, I have a single NiMH AA which I want to boost to 5v, I have previously used the MCP1640 for this. I'd like to build in charging from an external power source. The bq2002 looks like a decent, simple part and I could use both ICs. However I am wondering if there exists an IC that will provide both the boost regulation and charging. Perhaps my google magic is failing me, or maybe this doesn't exist. Is anybody aware of something suitable?
