the Allegro?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 μ? typical, providing low power loss.
The thickness of the copper conductor allows survival of the
device at high overcurrent conditions. The terminals of the
conductive path are electrically isolated from the signal leads
