ACS759 Series

Allegro MicroSystems' ACS759 is optimized for 3.3 V operation

Image of Allegro MicroSystems' ACS759 SeriesAllegro MicroSystems' ACS759 family of current sensors provides economical and precise solutions for AC or DC current sensing in 3.3 V supply applications. For 5 V, applications use the ACS758 family of parts. Typical applications include motor control, load detection and management, power supply and DC-to-DC converter control, inverter control, and overcurrent fault detection.

Features
  • 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, and prevents offset drift in high-side, high voltage applications
  • Output voltage proportional to AC or DC currents
  • Galvanic isolation allows for economical, high-side current sensing in high voltage system
  • Small package size, with easy mounting capability
  • Ultra-low power loss: 100 uΩ internal conductor resistance
  • Monolithic Hall IC for high reliability
  • 3 µs output rise time in response to step input current
  • Optimized test and programming at 3.3 V
  • Factory-trimmed for accuracy
  • Extremely stable output offset voltage
  • Nearly zero magnetic hysteresis
