High-Side Current Measurement: Circuits and Principles

Overview Current measurement (monitoring current flow into and out of electronic circuits) is an essential skill in the designer's repertoire and necessary in a wide range of applications. Examples include overcurrent-protection and supervising devices, 4-20mA systems, programmable current sources, linear and switch-mode power supplies, battery chargers, and battery-operated circuits for which you must know the ratio of current flow into and out of a rechargeable battery (that is, the gauge function).

As more applications become portable, the demand increases for dedicated current monitors that accomplish their task in a small package and with low quiescent current. The following discussion covers low-side and high-side current monitors and includes their architectures and applications.
