• It provides an analog output voltage proportional to the AC or DC current being measured.
• The device features a ratiometric output, ensuring accuracy across the supply voltage range.
• Designed for high-speed applications, it includes internal fault detection for overcurrent conditions.

Features:

• Low-Resistance Current Path (1.2 mΩ typical) for reduced power loss.
• Galvanic Isolation for improved noise immunity and safety.
• Ratiometric Output for stable performance across varying supply voltages.
• High Bandwidth (120 kHz) suitable for fast transient current measurements.
• Integrated Shield reduces current conductor dV/dt and EMI.
• Overcurrent Fault Detection with a programmable threshold.
• Small Form Factor (SOIC-8 package) for space-constrained applications.

This sensor is commonly used in motor control, power supplies, battery management, and industrial applications requiring precise current measurement.
