Coulomb Counter/

Battery Gas Gauge

DESCRIPTIO

FEATURES

TheLTC^®4150measuresbatterydepletionandchargingin

handheld PC and portable product applications. The de-

vice 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

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

The part also indicates charge polarity as the battery is

depleted or charged.
