The LTC ? 4150 measures battery depletion and charging
in handheld PC and portable product applications. The
device monitors current through an external sense resistor
between the battery’s positive terminal and the battery’s
load or charger. A voltage-to-frequency converter trans-
forms the current sense voltage into a series of output
pulses at the interrupt pin. These pulses correspond to a
?xed quantity of charge ?owing into or out of the battery.
The part also indicates charge polarity as the battery is
APPLICATIONS
depleted or charged.
