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).
The high CMR capability of the HCPL-7510 isolation amplifier provides the precision and stability needed to accurately monitor motor current in high noise motor control environments, providing for smoother control (less “torque ripple”) in various types of motor control applications.
Functional Diagram IDD1 VDD1 VIN+ VIN– GND1 1 2 3 4 SHIELD + – IDD2 8 7 6 5 VDD2 VOUT VREF GND2 + – The product can also be used for general analog signal isolation applications.
For general applications, we recommend the HCPL-7510 (gain tolerance of ±5%).
The HCPL-7510 utilizes sigma delta (S-D) analog-to-digital converter technology to delivery offset and gain accuracy and stability over time and temperature.
This performance is delivered in a compact, auto-insert, 8-pin DIP package that meets worldwide regulatory safety standards.
(A gull-wing surface mount option #300 is also available).
