ACS712

Fully Integrated, Hall Effect-Based Linear Current Sensor IC

with 2.1 kVRMS Isolation and a Low-Resistance Current Conductor

Features and Benefits

Description

The Allegro^™ACS712 provides economical and precise

solutionsforACorDCcurrentsensinginindustrial, commercial,

and communications systems. The device package allows for

easy implementation by the customer. Typical applications

includemotorcontrol,loaddetectionandmanagement,switch-

mode power supplies, and overcurrent fault protection. The

device is not intended for automotive applications.

Ratiometric output from supply voltage

The device consists of a precise, low-offset, linear Hall circuit

with a copper conduction path located near the surface of the

die. Applied current flowing through this copper conduction

close proximity of the magnetic signal to the Hall transducer.

A precise, proportional voltage is provided by the low-offset,

chopper-stabilized BiCMOS Hall IC, which is programmed

for accuracy after packaging.

The output of the device has a positive slope (>V_IOUT(Q)

)

when an increasing current flows through the primary copper

conduction path (from pins 1 and 2, to pins 3 and 4), which is

the path used for current sampling. The internal resistance of

this conductive path is 1.2 mΩ typical, providing low power

loss. The thickness of the copper conductor allows survival of

Application 1. The ACS712 outputs an analog signal, V_OUT

that varies linearly with the uni- or bi-directional AC or DC

primary sampled current, I_P, within the range specified. C_F

is recommended for noise management, with values that

depend on the application.
