  Dual Battery Power Manager Increases Run Time by 12%
  and Cuts Charge Time in Half – Design Note 277
  Mark Gurries Although a multibattery simultaneous charge and discharge system can be more difficult to implement than
  a sequential system, paralleling the charging and discharging dual batteries significantly reduces charge time
  and extends run time. The LTCВ®1960 solves many design
  complexities by placing all of the hard-to-design charge
  and discharge control functions in a single package,
  making implementation of dual battery management
  systems possible for a wide variety of applications. In
  addition to controlling simultaneous battery charging
  and discharging, it controls all PowerPathв„ў switching
  between the two batteries, the wall adapter and the
  equipment’s DC/DC converters, plus it includes many
  circuit protection functions. Figure 1 shows a block
  diagram of a typical application.
  The LTC1960 comprises two controllers: The PowerPath controller manages the delivery of power from the
  WALL
  ADAPTER
  INPUT SYSTEM POWER two batteries and a DC input supply while the charge
  controller manages charging the batteries.
  The heart of the PowerPath controller is the ideal diode
  circuit that allows precise voltage tracking between the
  batteries. The ideal diode circuit uses the same MOSFET …
