Microsemi announces a linear battery charger circuit for use in cell phones, pagers, digital cameras, GPS receivers, PDAs and single lithium-Ion cell chargers. Designated the LX2201™, the charger's highly integrated design requires three external resistors, and provides a full USB compliant charging current up to 2 A from a high power miniature surface mount package 4 millimeters square. Other features include an internal pass element that can function as a reverse direction load switch, full capacity charging with always-cool running, a conditioning mode for deep discharge, topping charge for long periods of non-use and a highly tolerant 5 V plus 10% wall supply regulation.
