双向电流检测与单输出

资料介绍
摘要:电池供电设备经常需要监视充电和放电电流。双电流检测放大器和差动放大器相结合,以产生一个单一的输出电压指示电池电流的大小和方向。

APPLICATION NOTE 1949
Bi-directional Current-Sense with Single Output

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
MA……
