“The Allegro™ACS710 current sensor provides economical and precise means for current sensing applications in industrial, commercial, and communications systems. The device is offered in a small footprint surface-mount package that allows easy implementation in customer applications.

Features and Benefits

â–ª Industry-leading noise performance with greatly improved
bandwidth through proprietary amplifier and filter design
techniques
â–ª Small footprint package suitable for space-constrained
applications
â–ª 1 mΩ primary conductor resistance for low power loss
â–ª High isolation voltage, suitable for line-powered
applications
â–ª User-adjustable Overcurrent Fault level
â–ª Overcurrent Fault signal typically responds to an
overcurrent condition in < 2 μs
â–ª Integrated shield virtually eliminates capacitive coupling
from current conductor to die due to high dV/dt voltage
transients
â–ª Filter pin capacitor improves resolution in low bandwidth
applications
â–ª 3 to 5.5 V single supply operation
â–ª Factory-trimmed sensitivity and quiescent output voltage
â–ª Chopper stabilization results in extremely stable quiescent
output voltage
â–ª Ratiometric output from supply voltage

Applications include:

• Motor control and protection
• Load management and overcurrent detection
• Power conversion and battery monitoring / UPS systems
