INTRODUCTION
Sensing and/or controlling current flow is a fundamental requirement in many electronics systems, and the
techniques to do so are as diverse as the applications
themselves. This Application Note compiles solutions to
current sensing problems and organizes the solutions by
general application type. These circuits have been culled
from a variety of Linear Technology documents.
Circuits Organized by General Application
Each chapter collects together applications that tend to
solve a similar general problem, such as high side current sensing, or negative supply sensing. The chapters are titled
accordingly. In this way, the reader has access to many
possible solutions to a particular problem in one place.
It is unlikely that any particular circuit shown will exactly
meet the requirements for a specific design, but the suggestion of many circuit techniques and devices should
prove useful. To avoid duplication, circuits relevant to
multiple chapters may appear in one location.
