ACS75050-DS Rev.4 Always order by complete part number: Always order by complete part number: ACS750SCA-050 ACS750LCA-050 The Allegro ACS750 family of current sensors provides economical and precise solutions for current sensing in industrial, commercial, automotive, and com- munications systems. The device package allows easy implementation by the customer. Typical applications include: motor control, load detection and man- agement, switched mode power supplies, and overcurrent fault protection. The sensor consists of a precision linear Hall IC, which is 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 pro- grammed 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. These power terminals also are electrically isolated from the sensor leads (pins 1, 2, and 3). This allows the ACS750 family of sen- sors to be used in applications requiring electrical isolation, without using opto- isolators or other costly isolation techniques. The output of this device has a positive slope (>VCC /2) when an increasing cur- rent flows from terminal 4 to terminal 5. The ACS750 family is lead-free. All leads are coated with 100% matte tin, and there is no lead inside the package. The heavy gauge leadframe is made of oxygen-free copper.
