Features and Benefits
▪ Industry-leading noise performance through proprietary
amplifier and filter design techniques
▪ Integrated shield greatly reduces capacitive coupling from
current conductor to die due to high dV/dt signals, and
prevents offset drift in high-side, high voltage applications
▪ Total output error improvement through gain and offset
trim over temperature
▪ Small package size, with easy mounting capability
▪ Monolithic Hall IC for high reliability
▪ Ultra-low power loss: 100 μΩ internal conductor resistance
▪ Galvanic isolation allows use in economical, high-side
current sensing in high voltage systems
▪ 3.0 to 5.5 V, single supply operation

Thermally Enhanced, Fully Integrated, Hall Effect-Based
Linear Current Sensor IC with 100 μΩ Current Conductor
Description
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, guarantees low output voltage ripple and low offset
drift in high-side, high voltage applications.
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 100 μΩ typical, providing low power loss.
The thickness of the copper conductor allows survival of the
device at high overcurrent conditions. The terminals of the
