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/s common-mode rejection at Vcm = 1000 V The HCPL-7520 isolated linear current sensing IC family is designed for current sensing in low-power electronic Compact, auto-insertable 8-pin DIP package motor drives. In a typical implementation, motor current 60 ppm/C gain drift vs. temperature flows through an external resistor and the resulting 0.6 mV input offset voltage analog voltage drop is sensed by the HCPL-7520. An 8 V/C input offset voltage vs. temperature output voltage is created on the other side of the HCPL- 7520 optical isolation barrier. This single-ended output 100 kHz bandwidth voltage is proportional to the motor current. Since 0.06% non-linearity, single-ended amplifier output for common-mode voltage swings of several hundred low power application. volts in tens of nanoseconds are common in modern Worldwide safety approval: switching inverter motor drives, the HCPL-7520 was UL 1577 (3750 Vrms/1 min.), CSA and IEC/EN/DIN EN designed to ignore very high common-mode transient 60747-5-2 (Option 060 only) slew rates (of at least 10 kV/s). Advanced sigma-delta () A/D converter The high CMR capability of the HCPL-7520 isolation technology amplifier provides the precision and stability needed to accurately monitor motor current in high noise motor Applications control environments, providing for smoother control Low-power inverter current sensing (less torque ripple) in various types of motor control Motor phase and rail current sensing applications. Switched mode power supply signal isolation The product can also be used for general analog signal General purpose low-power current sensing and isolation applications. For general applications, we monitoring recommend the HCPL-7520 (gain tolerance of 5%). General purpose analog signal isolation The HCPL-7520 utilizes sigma-delta () analog-to- Functional Diagram digital converter technology to delivery offset and gain accuracy and stability over time and temperature. This I I DD1 DD2 performance is delivered in a compact, auto-insert, 8- V 8 V DD1 1 DD2 pin DIP package that meets worldwide regulatory safety standards. (A gull-wing surface mount option 300 is also V 2 + 7 V IN+ + OUT available). V IN 3 6 V REF 4 GND1 5 GND2 SHIELD A 0.1 F bypass capacitor must be connected between pins 1 and 4 and between pins 5 and 8. CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and /or degradation which may be induced by ESD.Ordering Information HCPL-7520 is UL Recognized with 3750 Vrms for 1 minute per UL1577.
