Dual Battery Power Manager Increases Run Time by 12%
and Cuts Charge Time in Half вЂ“ Design Note 277
Mark Gurries Although a multibattery simultaneous charge and discharge system can be more difп¬Ѓcult to implement than
a sequential system, paralleling the charging and discharging dual batteries signiп¬Ѓcantly 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
equipmentвЂ™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 …
