HCPL-7520  
Isolated Linear Sensing IC  
Data Sheet  
Lead (Pb) Free  
RoHS 6 fully  
compliant  
RoHS 6 fully compliant options available;  
-xxxE denotes a lead-free product  
Description  
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  
The HCPL-7520 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-7520. An  
output voltage is created on the other side of the HCPL-  
7520 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-7520 was  
designed to ignore very high common-mode transient  
slew rates (of at least 10kV/µs).  
• 8 µV/°C input offset voltage vs. temperature  
• 100 kHz bandwidth  
• 0.06% non-linearity, 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  
technology  
The high CMR capability of the HCPL-7520 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.  
Applications  
• Low-power inverter current sensing  
• Motor phase and rail current sensing  
• Switched mode power supply signal isolation  
The product can also be used for general analog signal  
isolation applications. For general applications, we  
recommend the HCPL-7520 (gain tolerance of 5%).  
The HCPL-7520 utilizes sigma-delta (Σ−∆) 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).  
• General purpose low-power current sensing and  
monitoring  
• General purpose analog signal isolation
