LTC4150 Datasheet - Linear Technology

LTC4150 Coulomb Counter/ Battery Gas Gauge

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 sen.
