Low-Power, Dual Hall-Effect Sensor

Industry's First Dual Hall-Effect Sensor that Measures the Direction and Speed of an Applied Magnetic Field

Please check latest availability status for a specific part variant.


The MAX9641 is dual, low-power Hall-effect sensor. Using two sensors spaced apart on the die, it detects the direction and frequency of a magnetic field. The user can select one of three preset thresholds and one of three sampling rates to minimize power dissipation. The MAX9641 is offered in a 6-bump WLP (1.2mm x 1.7mm x 0.6mm).

Key Features

  • 1.7V to 5.5V Supply Voltage Range
  • Ultra-Low Supply Current
  • Adjustable Thresholds
  • Adjustable Duty Cycle
  • Direction Indicator
  • CMOS Output Eliminates the Need for an External Pull-Up Resistor
  • Tiny 1.2mm x 1.7mm, 6-Bump WLP
  • -40°C to +125°C Temperature Range
