Applications
• Motor phase and rail current sensing
• Power inverter current and voltage sensing

General
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.
