  Li-Ion Charge Termination IC Interfaces with PWM Switchers
  Design Note 242
  Fran Hoffart
  Rechargeable lithium-ion batteries are rapidly becoming the battery of choice for many battery-powered
  products. These products include notebook computers, PDAs, video camcorders, digital cameras, cellular
  phones, portable test equipment and others. Compared
  to other rechargeable power sources, Li-Ion batteries
  have higher energy density for both weight and volume
  and provide longer run time between charges. tery from overtemperature and overcurrent conditions.
  In addition, battery packs may also contain back-toback MOSFET switches that disconnect the battery if
  an overcurrent condition exists for either charge or
  discharge, or if an overvoltage or undervoltage condition exists. Many of these precautions are needed
  because lithium-ion cells are easily damaged by both
  overcharge and overdischarge conditions. Charging Li-Ion batteries is a relatively simple process.
  Apply a current-limited (at a 1C rate) constant voltage
  (В±1% tolerance) for approximately three hours, then
  stop charging. (C is a battery term used to indicate
  the Ampere-hour capacity of a battery). A complete
  charge cycle may also include precharge qualification
  for battery temperature and precharge qualification for
  deeply discharged batteries. LTВ®1510 Battery Charger IC
  The LT1510 is a high efficiency switching regulator
  power IC designed speciп¬Ѓcally for battery charging …
