HCPL-7510 - Isolated Linear Sensing IC

General Description

The HCPL-7510 isolated linear current sensing IC family is designed for current sensing in low-power electronic motor drives.

In a typical implementation, motor current flows through an external resistor and the resulting analog voltage drop is sensed by the HCPL-7510.

Key Features

  • 15 kV/µs common-mode rejection at Vcm = 1000 V.
  • Compact, auto-insertable 8-pin DIP package.
  • 60 ppm/°C gain drift vs. temperature.
  • 0.6 mV input offset voltage.
  • 8 µV/°C input offset voltage vs. temperature.
  • 100 kHz bandwidth.
  • 0.06% nonlinearity, single-ended amplifier output for low power.

www.DataSheet4U.com Agilent HCPL-7510 Isolated Linear Sensing IC Data Sheet Description The HCPL-7510 isolated linear current sensing IC family is designed for current sensing in low-power electronic motor drives. In a typical implementation, motor current flows through an external resistor and the resulting analog voltage drop is sensed by the HCPL-7510. An output voltage is created on the other side of the HCPL-7510 optical isolation barrier. This singleended output voltage is proportional to the motor current. Since common-mode voltage swings of several hundred volts in tens of nanoseconds are common in modern switching inverter motor drives, the HCPL-7510 was designed to ignore very high common-mode transient slew rates (of at least 10 kV/ µs).
