ACS37002 Datasheet High ACcuracy Current Sensor

Manufacturer: Allegro MicroSystems

Overview: ACS37002 400 kHz, High Accuracy Current Sensor with Pin-Selectable Gains and Adjustable Overcurrent Fast Fault in SOICW-16.

General Description

The ACS37002 is a fully integrated Hall-effect current sensor in an SOICW-16 package that is factory-trimmed to provide high accuracy over the entire operating range without the need for customer programming.

The current is sensed differentially by two Hall plates that subtract out interfering external commonmode magnetic fields.

The package construction provides high isolation by magnetically coupling the field generated by the current in the conductor to the monolithic Hall sensor IC which has no physical connection to the integrated current conductor.

Key Features

  • High operating bandwidth for fast control loops or where high-speed currents are monitored.
  • 400 kHz bandwidth.
  • 1.1 µs typical response time.
  • High accuracy.
  • ±1% maximum sensitivity error over temperature (K series).
  • ±8 mV maximum offset voltage over temperature.
  • Non-ratiometric operation with VREF output.
  • Low noise LA package ◊ 160 mVRMS for 3.3 V supply ◊ 124 mVRMS for 5 V supply.
  • Differential sensing for high immu.
