Description
The Allegro® ACS712 provides economical and precise solutions for
AC or DC 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 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. 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 after packaging.The output of the device
has a positive slope (>V IOUT(Q))
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. The internal resistance of this
conductive path is 1.2 mΩ typical, providing low power
Application
1. The ACS712 outputs an analog signal, VOUT. that varies linearly
with the uni- or bi-directional AC or DC primary sensed current,
IP, within the range specified. CF is recommended for noise
management, with values that depend on the application.
