Abstract: Battery operated devices often need to monitor both charge and discharge currents. A dual current-sense amplifier and differenTIal amplifier are combined to produce a single output voltage that indicates magnitude and direcTIon of battery current.   Systems such as laptop computers and other devices that have internal charge circuitry require a precise bi-direcTIonal current-sense amplifier to monitor accurately the battery‘s current regardless of polarity. The MAX4377 (a dual low-cost current-sense) can be used to produce a bi-direcTIonal current monitor.
