Allegro MicroSystems Europe has introduced a new family of bi-directional linear Hall-effect sensors that combine a 20 A dynamic range with an internal resistance of only one milliohm, an accuracy of better than 1,5% and an isolation voltage of 1600 V r.m.s. According to the company, the new ACS family surface mount SOIC8 package currently offers the smallest isolated integrated current-sensing solution on the market.
The ACS706 family are isolated integrated devices that provide precise and easy-to-implement solutions for current sensing in industrial, commercial, and communications systems. Typical applications include motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection.
The bi-directional sensors can measure either AC or DC currents, and feature a power lead frame which is designed for very low power loss. It is electrically isolated from the sensor signal leads, allowing the sensors to be used in applications requiring electrical isolation without the need for additional components.
Each device in the ACS706 family consists of a precision, low-offset linear Hall-effect sensor circuit with a copper conduction path near the surface of the die. Current flowing through this generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. A precise, proportional voltage is provided by the low-offset, chopper-stabilised BiCMOS Hall IC, which is pre-programmed for optimum accuracy at the factory.
The thickness of the copper conductor used in the sensor means that it can be safely used at up to three times the overcurrent conditions. The terminals of the conductive path are electrically isolated from the sensor leads.
