霍爾電流傳感器ACS706,pdf中文資料:The Allegro ACS706 family of current sensors provides economical and
precise solutions for current sensing in industrial, automotive, commercial, and
communications systems. The device package allows for easy implementation
by the customer. Typical applications include motor control, load detection and
management, switched-mode power supplies, and overcurrent fault protection.
The device consists of a precision, 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. Device
accuracy is optimized through the 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 at the
factory.
