      HCPL-7840-500E
      DescriptionThe HCPL-7840 isolation amplifer family was 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 HCPL-7840. A differential output voltage is created on the other side of the HCPL-7840 optical isolation barrier. This differential output voltage is proportional to the motor current and can be converted to a single-ended signal by using an op-amp as shown in the recommended application circuit. Since common-mode voltage swings of several hundred volts in tens of nanoseconds are common in modern switching inverter motor drives, the HCPL-7840 was designed to ignore very high common mode transient slew rates (of at least 10 kV/μs).The high CMR capability of the HCPL-7840 isolation amplifer provides the precision and stability needed to accurately monitor motor current in high noise motor control environ-ments, providing for smoother control (less “torque ripple”) in various types of motor control applications.Features● 15 kV/μs common-mode rejection at VCM = 1000 V● Compact, auto-insertable standard 8-pin DIP package● 0.00025 V/V/°C gain drift vs. temperature● 0.3 mV input offset voltage● 100 kHz bandwidth● 0.004% nonlinearity● Worldwide safety approval:UL 1577 (3750 Vrms/1 min.)and CSA, IEC/EN/DIN EN 60747-5-2● Advanced Sigma-Delta (∑-Δ) A/D converter technology● Fully differential circuit topology● 0.8 μm CMOS IC technologyApplications● Motor phase and rail current sensing● Inverter current sensing● Switched mode power supply signal isolation● General purpose current sensing and monitoring● General purpose analog signal isolation

      DescriptionThe HCPL-7800(A) isolation amplifer family was 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 HCPL-7800(A). A differential output voltage is created on the other side of the HCPL-7800(A) optical isolation barrier. This differential output voltage is pro portional to the motor current and can be converted to a single-ended signal by using an op-amp as shown in the recommended application circuit.

      HCPL-7510-500E
      DescriptionThe 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 single ended 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).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 application.• Worldwide safety approval: UL 1577 (3750 Vrms/1 min.), CSA and IEC/EN/DIN EN 60747-5-2 (Option 060 only)• Advanced sigma-delta (Σ-∆) A/D converter technologyApplications• Low-power inverter current sensing• Motor phase and rail current sensing• Switched mode power supply signal isolation• General purpose low-power current sensing and monitoring• General purpose analog signal isolation
