TDK-MicronasHAL1880 is an entry-level Hall-effect sensor with ratiometric analog output, offering the best compromise related to sensor function vs system cost. It includes programmable clamping to extend error signaling capability and diagnostics associated with the state of various internal circuits (magnetic signal out of range). A one-pin programming interface enables the simultaneous programming of several devices through the output pin.

The HAL1880 is a programmable sensor: major characteristics like magnetic field range, sensitivity, offset, and the temperature coefficients are programmable in nonvolatile memory. The sensor is designed for industrial and automotive applications, is AEC-Q100 qualified, and operates in the junction temperature range from -40°C up to +170°C. It is available in the very small leaded package TO92UA.

Features

  • Overvoltage and reverse-voltage protection at VSUP pin
  • Measurement ranges from ±20 mT to ±160 mT
  • Short-circuit protected push-pull output
  • 5 V supply operation
  • Selectable sampling rate
  • TJ = -40°C to +170°C
  • AEC-Q100 qualified

Benefits

  • Programmable temperature characteristics for matching all common magnetic materials
  • Programming via output pin or supply voltage modulation
  • Operates with static and dynamic magnetic fields up to 5 kHz
  • Selectable clamping levels for diagnostic
  • EMC and ESD optimized design
