ACS754xCB-200

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.

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
