Description

The Allegro

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 ACS716 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 ACS716 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, guarantees low ripple at 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

ACS716 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
