DESCRIPTION

The Allegro? ACS773 family of current sensor ICs provide

economical and precise solutions for AC or DC current sensing,

ideal for motor control, load detection and management, power

supply and DC-to-DC converter control, and inverter control.

The 2.5 μs response time enables overcurrent fault detection

in safety-critical applications.

The device consists of a precision, low-offset linear Hall

circuit with a copper conduction path located near the die.

Applied current flowing through this copper conduction path

generates a magnetic field which the Hall IC converts into a

proportional voltage. Device accuracy is optimized through the

close proximity of the magnetic signal to the Hall transducer.

A precise, proportional output voltage is provided by the

low-offset, chopper-stabilized BiCMOS Hall IC, which is

programmed for accuracy at the factory. Proprietary digital

temperature compensation technology greatly improves the

IC accuracy and temperature stability.

High-level immunity to current conductor dV/dt and stray

electric fields is offered by Allegro proprietary integrated shield

technology for low output voltage ripple and low offset drift

in high-side, high-voltage applications.
