HCPL - 7520

Isolated Linear Sensing IC

Data Sheet

Description

Features

The HCPL-7520 isolated linear current sensing IC family • 15 kV/µs common-mode rejection at Vcm = 1000 V

is designed for current sensing in low-power electronic

motor drives. In a typical implementation, motor cur-

rent ﬂows through an external resistor and the resulting

analog voltage drop is sensed by the HCPL-7520. An

• Compact, auto-insertable 8-pin DIP package

• 60 ppm/°C gain drift vs. temperature

• –0.6 mV input oﬀset voltage

output voltage is created on the other side of the HCPL- • 8 µV/°C input oﬀset voltage vs. temperature

7520 optical isolation barrier. This single-ended output

voltage is proportional to the motor current. Since com-

mon-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).

• 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 sig-

nal 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

SHIELD

A 0.1 µF 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 pre-

vent damage and /or degradation which may be induced by ESD.
