电流检测电路大全 APPLICATION NOTE―105 Application Note 105 December 2005 Current Sense Circuit Collection
Making Sense of Current Tim Regan, Editor 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 (see “Circuit Collection Index” below). In this
