Description:
The ACS758 family of current sensor ICs provides economical and precise
solutions for AC or DC current sensing.
Typical applications include motor control, load detection and management, power
supply and DC-to-DC converter control, inverter control, and overcurrent fault
detection.
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.
High level immunity to current conductor dV/dt and stray electric fields,
offered by Allegro proprietary integrated shield technology, provides low output
voltage ripple and low offset drift in high-side, high voltage applications.
The output of the device has a positive slope (>VCC/ 2) when an 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 100 µΩ typical, providing low power loss
