ACS37042 - Integrated Hall Effect Current Sensor

Download the ACS37042 datasheet PDF. This datasheet also covers the ACS37041 variant, as both devices belong to the same integrated hall effect current sensor family and are provided as variant models within a single manufacturer datasheet.

General Description

The ACS37041/2 is a small, integrated current sensor for cost-optimized applications.

Key Features

  • Self contained shuntless current sensing with no external sense resistor required; single package solution.
  • Low ohmic loss with 1.6 mΩ conductor resistance on the LH package.
  • Differential sensing robust against external magnetic fields.
  • Small footprint, SOT23-W 5-pin LH package.
  • 150 kHz analog output for fast response time.
  • Inherent galvanic isolation.
  • 100 VRMS functional isolation (ACS37041 only).
  • UL certified 285 VRMS bas.
