DESIGN IDEASвЂ‰L 3-in-1 Device Replaces Battery
Charger, Overvoltage Protection
and PowerPath Manager for
USB/Battery Powered Devices
by Andy Bishop Introduction
An efficient Li-Ion battery powered
system requires at least three distinct
circuits to control the power path
between the load, the battery and the
power source (see FigureВ 1). The minimal circuit requirements include:
q a battery charger,
q a power switch to select powering
the load from either the battery or
the wall adapter (when present),
q and a current regulator for the
wall adapter/USB input.
This, of course, assumes that the
load draws power from a communal
power bus, as opposed to attaching
directly and exclusively to the battery.
A direct-to-battery topology might be
simpler, precluding the need for the
power path controller and regulator, …
