TLP7820
TLP7820
1. Applications
• Motor phase and rail current sensing
• Power inverter current and voltage sensing
2. 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.
3. Features
(1) Output side supply voltage: 3 to 5.5 V
(2) Output side supply current: 6.2 mA (typ.)
(3) Operating temperature range: -40 to 105
(4) Common-mode transient immunity: 15 kV/µs (min)
4. Packaging and Pin Assignment
