Description

The (llegro: (,;%* provides economical and precisesolutions .or (, or D, current sensing in industrial/

commercial/ and communications sstems& The device

pac"age allows .or eas implementation b the customer&

Tpical applications include motor control/ load detection

and management/ switched-mode power supplies/ and

overcurrent .ault protection&

The device consists o. a precise/ low-o..set/ linear #all

sensor circuit with a copper conduction path located near the

sur.ace o. the die& (pplied current .lowing through this

copper conduction path generates a magnetic .ield which is

sensed b the integrated #all I, and converted into a

proportional voltage& Device accurac is optimi$ed throughthe close pro8imit o. the magnetic signal to the #all

transducer& ( precise/ proportional voltage is provided b

the low-o..set/ chopper-stabili$ed
