The Allegro ACS750 family of current sensors provides economical and precise solutions for current sensing in industrial, commercial, automotive, and communications systems. The device package allows for easy implementation by the customer. Typical applications include motor control, load detection and management, switched mode power supplies and over-current fault protection. The sensor consists of a precision linear Hall IC optimized to an internal magnetic circuit to increase device sensitivity. The combination of a precisely controlled self-aligning assembly process (patents pending) and the factory programmed precision of the linear Hall sensor result in high level performance and product uniformity.
The primary conductor used for current sensing (terminals 4 and 5) is designed for extremely low power loss. The power terminals are also electrically isolated from the sensor leads (pins 1 – 3). This allows the ACS750 family of sensors to be used in applications requiring electrical isolation without the use of opto-isolators or other costly isolation techniques.
The output of the device has a positive slope (>Vcc/2) when an increasing current flows from terminal 4 to terminal 5.
