Low Resistance, High Power Density Current Sensor in QFN or Widebody SOIC-6 Package

ACS37220

ACS37220

The ACS37220 is a high-power-density magnetic current sensor offered in two package options. The 4x4mm QFN package supports up to 200A and is designed to replace high-power sense resistors in high-current monitoring applications requiring an isolation voltage below 100V. The widebody fused-lead SOIC-6 package supports up to 60A and 565VRMS Reinforced Isolation.

Packaging

The ACS37220 is a high-power-density, 150kHz magnetic current sensor offered in two package options.

The EZ 4x4mm QFN package option is designed to replace high-power sense resistors with a solution that achieves lower resistance, a smaller footprint and simpler integration. This package measures currents up to 200A and includes overcurrent fault output with user-configurable threshold to provide fast short-circuit detection for enhanced system protection. It is ideal for low voltage (<100V), high current monitoring applications and in-line current sensing in motor drives.

For applications requiring Basic or Reinforced Isolation, the MZ widebody fused-lead SOIC-6 package measures currents up to 60A and supports a similar Reinforced Isolation rating to comparable SOICW-16 packages in just half the size. This package supports up to 565VRMS Reinforced Isolation and 1097VRMS Basic Isolation.

  • AEC-Q100 Grade 0 qualified
  • Small footprint, 4 mm × 4 mm QFN “EZ” package with wettable flank, features overcurrent fault output with user-configurable threshold to provide fast short-circuit detection for enhanced system protection
  • Widebody fused-lead SOIC-6 “MZ” package supports a similar Reinforced Isolation rating to comparable SOICW-16 packages in just half the size

The ACS37220 is offered in two package options.

The small footprint 7-pin “EZ” package is a 4x4mm QFN with wettable flank and features a low internal conductor resistance of 100 μΩ for low power loss and high inrush current withstand capability. This package is designed to measure currents up to 200A and is suitable for applications requiring an isolation voltage below 100V.

The widebody fused-lead SOIC-6 “MZ” package measures currents up to 60A and supports a similar Reinforced Isolation rating to comparable SOICW-16 packages in just half the size. This package supports up to 565VRMS Reinforced Isolation and 1097VRMS Basic Isolation.
