The Allegro ? ACS713 provides economical and precise
solutions for DC current sensing in industrial, commercial, and
communications systems. The device package allows for easy
implementation by the customer. Typical applications include
motor control, load detection and management, switch-mode
power supplies, and overcurrent fault protection. The device
is not intended for automotive applications.
The device consists of a precise, low-offset, linear Hall 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 the Hall IC converts 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 sampling. The internal resistance of
this conductive path is 1.2 m Ω typical, providing low power
loss. The thickness of the copper conductor allows survival of
