Eko Lisuwandi The market for rechargeable batteries in consumer electronics has
reached a level of stable maturity, where designing a battery charger
requires little more effort than dropping a purpose-built battery
charger IC into the design. This is because the batteries in consumer
electronics follow well-worn standards, with popular configurations,
float voltages, charge currents, output voltages and charge
algorithms. Even so, there is an ever-growing demand for batteries
that donвЂ™t fit these standard molds. Much of this demand is driven by
industrial green initiatives, coupled with
a general move to portable equipment
in medical and other specialized fields.
Dedicated charger ICs canвЂ™t keep pace with the current explosion in application diversity. The growing variety of battery setups is simply too extensive,
ranging from kilowatt-powered indoor forklifts and …
