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.
