Top Features

Packaging

  • Proprietary segmented linear temperature compensation (TC) technology provides a typical accuracy of 1% over the full operating temperature range
  • Self-Test diagnostic mode can be used to achieve a high level of functional safety within a system
  • 120 kHz nominal bandwidth achieved via proprietary packaging and chopper stabilization techniques
  • Over Field Fault signal with 6-bit programmable trigger levels, 2-bit programmable hysteresis, and latching or non-latching behavior
  • Over Field Fault response time < 4.5 μs (typ)
  • Extremely low noise and high resolution achieved via proprietary Hall element and low-noise amplifier circuits
  • Customer-programmable, high-resolution offset and sensitivity trim
  • Available in a 1-mm-thick SIP through-hole package
  • Factory-programmed sensitivity and quiescent output voltage TC with extremely stable temperature performance
  • Selectable sensitivity range between 0.6 and 14 mV/G through use of coarse sensitivity program bits
  • Ratiometric sensitivity, quiescent voltage output, and clamps enable simple interface with application A-to-D converter (ADC)
  • Output voltage clamps provide short-circuit diagnostic capabilities
  • Open-circuit detection on ground pin (broken wire)
  • Undervoltage lockout for VCC below specification
  • Wide ambient temperature range: –40°C to 150°C

The A1365 sensor IC is provided in an extremely thin case (1 mm thick), 4-pin SIP (single inline package, suffix KT) that is lead (Pb) free, with 100% matte-tin leadframe plating.
