Top Features

Typical Applications

Packaging

  • Factory-programmed segmented linear temperature compensation (TC) provides ultralow thermal drift
    • Sensitivity error ±1%
    • Offset error ±5 mV
  • On-board supply regulator with reverse-battery protection provides high immunity to electrical overstress (EOS)
  • Very fast response time (2 µs)
  • High operating bandwidth: DC to 240 kHz
  • AEC-Q100 Grade 0, automotive qualified
  • Customer-programmable, high-resolution offset, and sensitivity trim
  • Extremely low noise and high resolution achieved via proprietary Hall element and low-noise amplifier circuits

The ACS70312 sensor IC is provided in an extremely thin case (1 mm thick), 4-pin SIP (single in-line package, suffix KT). Packages are lead (Pb) free, with 100% matte tin leadframe plating.
