ACS752SCA-100

Current Sensor: ACS752SCA-100 The Allegro ACS752 family of current sensors provides economical and precise solutions for current sensing in industrial, commercial, and communications systems. The device package allows easy implementation by the customer. Typical applications include: motor control, load detection and management, 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 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. These power terminals also are electrically isolated from the sensor leads (pins 1, 2, and 3). This allows the ACS752 family of sensors to be used in applications requiring electrical isolation, without using optoisolators or other costly isolation techniques. The output of this device has a positive slope (>VCC / 2) when an increasing current flows from terminal 4 to terminal 5. 4 5 1 2 3 Pin 1: VCC Pin 2: Gnd Pin 3: Output Terminal 4: Ip+ Terminal 5: Ip- ABSOLUTE MAXIMUM RATINGS Operating Temperature S ..................................................... –20 to +85ºC Supply Voltage, Vcc........................................... 16...
