  4A Li-Ion Battery Charger Accepts Inputs to 32V
  Rick Brewster Advances in Li-ion battery technologies continue to produce batteries with increased
  capacity and energy density. Charge/discharge rate capabilities are also rising,
  sometimes to multiple C rates (C is the standard designator for battery capacity
  stated in amp-hrs). These technologies are making their way into consumer,
  automotive, medical and industrial markets. In most cases, the charger must
  be able to recharge multiple sources over a wide range of input voltages.
  High capacity/current batteries require
  chargers that handle the high currents
  safely, efficiently and cost effectively.
  Until now, building a safe high current battery charger required the use
  of multiple ICs and a host of external
  components resulting in expensive and
  bulky solutions. The LT3651 integrated
  battery charger solves this problem
  by supporting charge currents up to
  4A and accepting input voltages to 32V.
  BATTERY CHARGER FEATURES Charger safety is a significant concern
  as batteries increase in capacity. The
  LT3651 includes all of the necessary charge
  termination and protection features.
  Charge termination methods include
  C/10 termination or safety timer termination. Additional protection features …
