ACS724

Automotive-Grade, Galvanically Isolated Current Sensor IC

With Common-Mode Field Rejection in a Small-Footprint SOIC8 Package

FEATURES AND BENEFITS

• AEC-Q100 qualified

DESCRIPTION

TheAllegro^™ACS724 current sensor IC is an economical and

precise solution for AC or DC current sensing in industrial,

automotive, commercial, and communications systems. The

small package is ideal for space-constrained applications

while also saving costs due to reduced board area. Typical

applications include motor control, load detection and

management, switched-mode power supplies, and overcurrent

fault protection.

• Differential Hall sensing rejects common-mode fields

• 1.2 mΩ primary conductor resistance for low power loss

and high inrush current withstand capability

• Integrated shield virtually eliminates capacitive

coupling from current conductor to die, greatly

suppressing output noise due to high dv/dt transients

• Industry-leading noise performance with greatly

improved bandwidth through proprietary amplifier and

filter design techniques

• High-bandwidth 120 kHz analog output for faster

response times in control applications

• Filter pin allows user to filter the output for improved

resolution at lower bandwidth

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

sensor circuit with a copper conduction path located near the

surface of the die.Applied current flowing through this copper

conduction path generates a magnetic field which is sensed

by the integrated Hall IC and converted into a proportional

voltage. The current is sensed differentially in order to reject

common-mode fields, improving accuracy in magnetically

noisyenvironments.Theinherentdeviceaccuracyisoptimized

through the close proximity of the magnetic field 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 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 sensing.

Theinternalresistanceofthisconductivepathis1.2mΩtypical,

providing low power loss.

• Patented integrated digital temperature compensation

circuitry allows for near closed loop accuracy over

temperature in an open loop sensor

• Small-footprint, low-profile SOIC8 package suitable for

space-constrained applications

• Filter pin simplifies bandwidth limiting for better

resolution at lower frequencies
