LTC4150 Datasheet Coulomb Counter/ Battery Gas Gauge

Manufacturer: Linear Technology (now Analog Devices)

General Description

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 transforms the current sense voltage into a series of output pulses at the interrupt pin.
