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) Gain accuracy: ±0.5 % (Gain rank B) (2) Gain drift: 0.00012 V/V/ (typ.) (3) Nonlinearity (VIN = ±200 mV): 0.02 % (typ.) (4) Input offset voltage: 0.9 mV (typ.) (5) VOUT bandwidth (-3 dB): 230 kHz (typ.) (6) Operating temperature range: -40 to 105 (7) Common-mode transient immunity: 15 kV/µs (min) (8) Safety standards
