DESCRIPTION
The SS400 Series sensor ICs are small, versatile, digital Halleffect devices that are operated by the magnetic field from a permanent magnet or an electromagnet, and are designed to respond to alternating North and South poles or to a South pole only. Bipolar, latching and unipolar magnetics are available.
Band gap regulation provides stable operation over 3.8 Vdc to 30 Vdc supply voltage range. These sensors are capable of continuous 20 mA sinking output and may be cycled as high as 50 mA max. Its 3.8 V capability allows for use in many potential low voltage applications. 

FEATURES AND BENEFITS
• Quad-Hall IC design minimizes mechanical stress effects
• Temperature-compensated magnetics helps provide stable
   operation over a wide temperature range of -40 ° to 150 °C
• Miniature standard 3-lead plastic package with tape option
   for automated component placement, potentially reducing
   installation costs
• Broad supply voltage capability from 3.8 Vdc to 30 Vdc for
   application flexibility
• Digital, open collector sinking output for easy interfacing
   with a variety of common electronic circuits
