Thermally Enhanced, Fully Integrated, Hall-Effect-Based Linear Current Sensor IC with 100 µΩ Current Conductor
1 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 • Ultralow power loss:100
µΩ internal conductor resistance
• Galvanic isolation allows use in economical, high-side current
sensing in high-voltage systems
• AEC-Q100 qualified
2 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, 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. 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
