2 DESCRIPTION
The Allegro™ ACS710 current sensor provides economical and precise
means for current sensing applications in industrial, commercial,
and communications systems. The device is offered in a small
footprint surface-mount package that allows easy implementation in
customer applications.
The ACS710 consists of a precision linear Hall sensor integrated
circuit with a copper conduction path located near the surface of
the silicon die. Applied current flows through the copper
conduction path, and the analog output voltage from the Hall sensor
linearly tracks the magnetic field generated by the applied
current. The accuracy of the ACS710 is maximized with this patented
packaging configuration because the Hall element is situated in
extremely close proximity to the current to be measured. High-level
immunity to current conductor dV/dt and stray electric fields,
offered by Allegro proprietary integrated shield technology,
results in low ripple on the output and low offset drift in
high-side, high-voltage applications.
The voltage on the Overcurrent Input (VOC pin) allows customers to
define an overcurrent fault threshold for the device. When the
current flowing through the copper conduction path (between the IP+
and IP– pins) exceeds this threshold, the open drain Overcurrent
Fault pin will transition to a logic low state. Factory programming
of the linear Hall sensor inside of the ACS710 results in
exceptional accuracy in both analog and digital output signals. The
internal resistance of the copper path used for current sensing is
typically 1 mΩ, for low power loss. Also, the current conduction
path is electrically isolated from the low-voltage
