Coulomb Counter/

Battery Gas Gauge

FEATURES

DESCRIPTION

The LTC^®4150 measures battery depletion and charging

in handheld PC and portable product applications. The

devicemonitorscurrentthroughanexternalsenseresistor

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

ﬁxed quantity of charge ﬂowing into or out of the battery.

The part also indicates charge polarity as the battery is

depleted or charged.
