SC1133 Unipolar Switch Hall Sensor IC



The SC1133 Hall-Effect switch series is monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150℃, and are more stable with both temperature and supply voltage changes. The negative compensation slope is optimized to match the negative temperature coefficient of low cost magnets.
Each device includes a voltage regulator for operation with supply voltages of 3.8 to 40V volts, quadratic Hall-voltage generator, temperature compensation circuitry, small-signal amplifier, Schmitt trigger, and an open-collector output to sink up to 40mA.


  • 3.8 to 40V supply voltage
  • High transient voltage protection
  • 40mA sinking capability
  • High ESD rating
  • 3-pin SIP and 3-pin SOT89 packages are available
  • RoHs compliant
