ACS710: 120 kHz Bandwidth, High Voltage Isolation Current Sensor IC with Integrated Overcurrent Detection

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, guarantees low ripple at output and low offset drift in high-side, high voltage applications.

The voltage on the Overcurrent Input (VOC pin) allows 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.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

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 sensor inputs and outputs. This allows the ACS710 family of sensors to be used in applications requiring electrical isolation, without the use of opto-isolators or other costly isolation techniques.

The ACS710 is provided in a small, surface mount SOIC16 package. The leadframe is plated with 100% matte tin, which is compatible with standard lead (Pb) free printed circuit board assembly processes. Internally, the device is Pb-free, except for flip-chip high-temperature Pb-based solder balls, currently exempt from RoHS. The device is fully calibrated prior to shipment from the factory
