device offers two operational amplifiers and a voltage reference, thus allowing the regulation
of both output voltage and current. An integrated OR function performs the combination of
the two resulting error signals, leading to a dual voltage and current limitation, known as a
rectangular output characteristic. This type of power supply is especially useful for battery
chargers where the output is mainly used in current mode, in order to deliver a defined
charging rate. The accurate voltage regulation is also convenient for Li-ion batteries which
require both modes of operation.
