ACS724LMA

Automotive Grade, High-Accuracy, Hall-Effect-Based Current Sensor IC with

Common-Mode Field Rejection in High-Isolation SOIC16 Package

DESCRIPTION

FEATURES AND BENEFITS

• AEC-Q100 automotive qualified

TheAllegro^™ACS724LMAcurrentsensorICisaneconomical

andprecisesolutionforACorDCcurrentsensinginautomotive,

industrial,commercial,andcommunicationsystems.Thesmall

package is ideal for space-constrained applications while also

saving costs due to reduced board area. Typical applications

includeelectricvehicleson-boardchargers, motorcontrol,load

detection and management, switched-mode power supplies,

and overcurrent fault protection.

• Differential Hall sensing rejects common-mode fields

• Patented integrated digital temperature compensation

circuitry allows for near closed loop accuracy over

temperature in an open loop sensor

• UL60950-1 (ed. 2) certification (pending)

□ Dielectric Strength Voltage = 4.8 kV_RMS

□ Basic Isolation Working Voltage = 1097 V_RMS

□ Reinforced Isolation Working Voltage = 565 V_RMS

• Industry-leading noise performance with greatly

improved bandwidth through proprietary amplifier and

filter design techniques

• Filter pin allows user to filter output for improved

resolution at lower bandwidth

• 0.85 mΩ primary conductor resistance for low power

loss and high inrush current withstand capability

• Low-profile SOIC16 package suitable for space-

constrained applications

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-stabilizedBiCMOSHallIC,whichincludes

Allegro’spatenteddigitaltemperaturecompensation,resulting

inextremelyaccurateperformanceovertemperature.Theoutput

of the device has a positive slope when an increasing current

flows through the primary copper conduction path (from pins

1 through 4, to pins 5 through 8), which is the path used for

current sensing. The internal resistance of this conductive path

is 0.85 mΩ typical, providing low power loss.

• 4.5 to 5.5 V single supply operation

• Output voltage proportional to AC or DC current

• Factory-trimmed sensitivity and quiescent output voltage

for improved accuracy

• Chopper stabilization results in extremely stable

quiescent output voltage

• Nearly zero magnetic hysteresis

• Ratiometric output from supply voltage

PACKAGE: 16-pin SOICW (suffix MA)

The terminals of the conductive path are electrically isolated

from the sensor leads (pins 9 through 16). This allows the

ACS724LMAcurrent sensor IC to be used in high-side current

sense applications without the use of high-side differential

amplifiers or other costly isolation techniques.
