The Allegro Current Sensor
provides an economical and precise
solution for current sensing in automotive and industrial systems,
packaged for easy implementation. Typical applications include
motor control, load 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. A 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 power lead frame used for current sensing (pins 4 and 5) is
designed for extremely low power loss. The power leads are also
electrically isolated from the sensor leads (pins 1 – 3). This isolation
allows the Allegro Current Sensor to be used in applications
requiring electrical isolation without the use of opto-isolators or other
isolating feedback techniques.
An electrical current flowing from pins 4 to 5 will generate an analog
voltage >Vcc/2 on the output.
