Current Sensor: ACS750xCA-075
5
4
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.
