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 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 (S-D) 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 -
