Low-cost LiPo Charger

The charging of Lithium-Polymer (LiPo) cells takes place very differently to that of the well known NiCd and NiMH cells. This aspect has previously been covered in Elektor Electronics. And this isn't the first LiPo charger that we've published, but it is undoubtedly the smallest! Chip manufacturer Intersil has designed a LiPo charger IC that requires a minimum of external components.
