Top Features

Typical Applications

Packaging

  • GMR technology integrates high sensitivity MR (magnetoresistive) sensor elements and high precision BiCMOS circuits on a single silicon integrated circuit, offering high accuracy, low magnetic field operation
  • Integrated capacitor in a single overmolded miniature package provides greater EMC robustness
  • SolidSpeed Digital Architecture™ supports advanced algorithms, maintaining performance in the presence of extreme system-level disturbances, including vibration immunity capability over the full target pitch
  • Flexible orientation for xMR or Hall replacement
  • ASIL B(D) rating based on integrated diagnostics and certified safety design process
  • Two-wire current source output pulse-width protocol supporting speed, direction, and ASIL
  • EEPROM offers device traceability throughout the production process

The A19350 is available in a lead (Pb) free 2-pin SIP (Suffix UB) package with a 100% matte tin plated leadframe.
