Top Features

Packaging

  • 2D magnetic sensing via planar and vertical Hall elements
    • Quadrature outputs
    • 90° phase separation between channels
  • Dual-channel output allows independent use of Z-axis planar Hall in conjunction with vertical Hall:
    • Y-axis (default option)
    • X-axis (with -X option)
  • High sensitivity, BOP typically 17 G
  • Automotive grade
    • AEC-Q100 qualified for use in automotive applications (L temperature range option)
    • Output short-circuit protection
    • Resistant to physical stress
    • Reverse-battery protection
    • Superior temperature stability
    • Supply voltage Zener clamp
  • Small size

The A1262 is available in a 5-pin SOT23W surface-mount package (LH) and a 4 pin SIP package (K). Each is offered in two options for a variety of magnet to sensor orientations. The packages are RoHS compliant and lead (Pb) free, with 100% matte-tin leadframe plating.
