双电流检测放大器简化H桥负载监控

采用正确的放大器对于设计H桥驱动器的负载电流监控并不困难，LTC6103和LTC6104完全符合这一设计要求。它们具有双检测输入和一个可选差分输出配置，这个特性可减小设计难度和电路板面积。advertisementDualCurrent-SenseAmpliersSimplifyH-BridgeLoadMonitoringDesignNote407JonMunsonIntroductionAfarmorepracticalmethodistomonitorthesupplyTheH-bridgepower-transistortopologyisincreasinglycurrentfedtoeachhalf-bridgeasshowninFigure2.popularasameansofdrivingmotorsandotherloadsbi-Thisschemeprovidesseveralbenetsthatsimplifyanddirectionallyfromasinglesupplypotential.Inmostcasesimprovethecircuitperformance.Themainimprovementthereisgreatbenetinmonitoringthecurrentdeliveredcomesfromhavingthesenseresistorsatarelativelytotheloadandutilizingthisinformationinreal-timeto
