Yes, I've used MCP73811 (not 73812) in a few (low quantity) projects with success. I've used them in circuits asking for up to 150mA while charging a 1000mAh lipo. It works really nice and that include testing done to revive deep descharge= d battery. Regards Ariel Rocholl 2010/9/21 PICdude > Excellent.
