Overview
ACS730LLC Automotive-Grade, 1 MHz Bandwidth, Galvanically Isolated Current Sensor IC in Small Footprint SOIC8 Package FEATURES AND BENEFITS • AEC-Q100 automotive qualified • Industry-leading noise performance with greatly improved bandwidth through proprietary amplifier and filter design techniques • High bandwidth 1 MHz analog output • Patented integrated digital temperature compensation circuitry allows high accuracy over temperature in an open loop sensor • 1.
2 mΩ primary conductor resistance for low power loss and high inrush current withstanding capability • Small footprint, low-profile SOIC8 package suitable for space-constrained applications • Integrated shield virtually eliminates capacitive coupling from current conductor to die due to high dV/dt voltage transients • 5 V single supply operation • Output voltage proportional to AC or DC current • Factory-trimmed sensitivity and quiescent output voltage for improved accuracy • High PSRR for noisy environments PACKAGE: 8-Pin SOIC (suffix LC) TÜV America Certificate Number: U8V 14 11 54214 032 CB 14 11 54214 031 Not to scale CB Certificate Number: US-22334-A2-UL DESCRIPTION The Allegro™ ACS730 provides economical and precise solutions for AC or DC current sensing in automotive, industrial, commercial, and communications systems.
The device package allows for easy implementation by the customer.
Typical applications include on-board chargers (OBC), DC-to-DC converters, motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection.
The device consists of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface of the die.
Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage.
Device accuracy is optimized through the close proximity of the magnetic field to the Hall transducer.
A precise, proportional...
