Description
TheAllegroACS710 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.
TheACS710 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
