DESCRIPTION

· The Broadcom® ACHS-719x is a fully integrated Hall-effect based isolated linear current sensor designed for AC or DC current sensing in industrial, commercial, and communications systems.

· It features a precise, low-offset, linear Hall circuit with a copper conduction path near the die surface, converting applied current into a proportional voltage.

· The device offers optimized accuracy across operating temperatures and is packaged in a compact, surface-mountable SO-8 package meeting global safety standards.

FEATURES

· Wide operating temperature: –40ºC to +110ºC.

· Internal conductor resistance: 0.7 mΩ typical.

· Sensing current range: ±10A to ±50A.

· Output sensitivity: 40 mV/A to 185 mV/A.

· Single supply operation: 5.0V.

· Device bandwidth: 80 kHz typical with 1-nF filter capacitor.

· Factory-trimmed for accuracy and stable output offset voltage.

· Maximum output error: ±6.0% across operating temperature.

· Common mode transient immunity: >25 kV/µs.

· Worldwide safety approval: UL/cUL, IEC/EN 62368-1 (Viorm = 567 Vpeak).
