DESCRIPTION
The Allegro™ ACS72981 family of current sensor ICs provides
economical and precise solutions for AC or DC current sensing.
A 250 kHz bandwidth makes it ideal for motor control, load
detection and management, power supply and DC-to-DC
converter control, and inverter control. The <2 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
zero output voltage and output sensitivity accuracy over
temperature and lifetime.
The output of the device increases when an increasing current
flows through the primary copper conduction path (from
terminal 5 to terminal 6), which is the path used for current
sampling. The internal resistance of this conductive path is
200 μΩ typical, providing low power loss and increasing power
density in the application.
The sensor employs differential sensing techniques that virtually
eliminate output disturbance due to common-mode interfering magnetic field.
