Top Features

Packaging

  • ±1.5% sensitivity error across temperature
  • Fused-lead SOIC-6 package supports 840 VRMS basic isolation and 420 VRMS reinforced isolation
  • Non-ratiometric operation with VREF output for enhanced accuracy in noisy environments (ACS37010)
  • Fast logic alert fault output pin with factory pre-programmed trip point provides overcurrent or short-circuit detection and enhanced system protection (ACS37012)
  • 0.68 mΩ internal primary conductor resistance for better power efficiency

The ACS37010 and ACS37012 are offered in the LZ fused-lead SOIC-6 package, which shares the same footprint as a standard SOIC-8. This package provides 420 VRMS reinforced isolation and up to 840VRMS basic isolation in a compact and more cost effective package versus comparable SOICW-16 packages. The LZ package has lower conductor resistance and supports higher isolation versus standard SOIC-8 packages.
