Description
The Allegro ACS75x family of current sensor ICs provides
economical and precise solutions for current sensing in
industrial, automotive, commercial, and communications
systems. The device package allows for easy implementation by
the customer. Typical applications include motor control, load
detection and management, power supplies, and overcurrent
fault protection.
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 voltage is provided by the low-offset,
chopper-stabilized BiCMOS Hall IC, which is programmed
for accuracy at the factory.
The output of the device has a positive slope (>V
increasing current flows through the primary copper conduction
path (from terminal 4 to terminal 5), which is the path used for
current sampling. The internal resistance of this conductive path
is typically 100 μΩ, providing low power loss. The thickness
of the copper conductor allows survival of the device at up to
