I've been looking around, and it seems that Sparkfun has chosen the Microchip MCP73831 (http://ww1.microchip.com/downloads/en/DeviceDoc/21984e.pdf) for their LiPo chargers. Seems ok to me, though I'm not an expert. It does lack the high/low setting that was on the MAX1811 that allowed me to start with a lower charge rate, then crank it up when I got approval from the USB host. Still poking around for protection circuits, and steers to good manufacturers would be appreciated. Thanks!
