Coreless, High Precision, Hall-Effect Current Sensor IC

with Common-Mode Field Rejection and High Bandwidth (240 kHz)

FEATURES AND BENEFITS

DESCRIPTION

• Eliminates need for concentrator core or shield

• Suited for applications where current flows through

busbar or PCB

• Very wide sensing range (2.5 to 20 mV/G)

□ Ideal for sensing currents from <200 A to >1000 A

• Factory-programmed segmented linear temperature

compensation (TC) provides low thermal drift

□ Sensitivity ±1% (typ)

□ Offset ±3 mV (typ)

• Differential Hall sensing rejects common-mode

magnetic fields

• High operating bandwidth: DC to 240 kHz

• AEC-Q100 Grade 0, automotive qualified

• Contactless, lossless, non-invasive current sensing

• Very fast response time (<2 μs typ)

• 3.3 or 5.0 V single supply operation

• Ratiometric output with unidirectional and

bidirectional modes

The Allegro ACS37612 current sensor IC enables low-cost

solutions for AC and DC current sensing without the need for

an external field concentrator core or shield. It is designed for

applications where hundreds of amps flow through a busbar

or PCB.

Applied current through a busbar or PCB traces generates a

magnetic field that is sensed by the monolithic, low-offset,

linear Hall IC. The differential sensing topology virtually

eliminates all types of errors due to common-mode stray

magnetic fields. High isolation is achieved via the no-contact

nature of this simple assembly.

TheACS37612 is offered in 140 kHz and 240 kHz bandwidth

options, making it ideal for inverter phase current sensing,

load detection and management, power supplies, and DC/

DC converters where fast switching is required. The high

response time enables overcurrent fault detection in safety-

critical applications. A –40°C to 150°C ambient operating

temperature range and a stellar ESD rating make it ready for

harsh automotive environments.

• Immune to mechanical stress

• Monolithic Hall IC for high reliability

• Wide ambient temperature range: –40°C to 150°C

• Surface mount, small footprint, low-profile

TSSOP8 package

TheACS37612 is suitable for space-constrained applications

becauseofitslow-profile8-pinsurfacemountTSSOPpackage

(thin-shrink small outline package, suffix LU) that is lead

(Pb) free, with 100% matte tin leadframe plating.
