ApplicationsApplications Motor phase and rail current sensing Power inverter current and voltage sensing 2. 2. 2. 2. GeneralGeneralGeneralGeneral The TLP7820 of isolation amplifiers is designed for current sensing in electronic motor drives. In a typical implementation, motor currents flow through an external resistor and the resulting analog voltage drop is sensed by the TLP7820. 3. 3. FeaturesFeatures 3. 3.
