DESCRIPTION
The SS360PT/SS460P High Sensitivity Latching Hall-Effect Sensor ICs with Built-in Pull-up Resistor are small, sensitive and versatile devices that are operated by the magnetic field from a permanent magnet or an electromagnet. They are designed to respond to alternating North and South poles. The SS360PT is activated by a North pole while the SS460P is activated by a South pole.

FEATURES AND BENEFITS
• Fastest response time in its class: Provides more efficiency
   in commutating a brushless dc motor
• No chopper stabilization: Results in a clean output signal
• High sensitivity: Operates from only 30 Gauss typical, at
   25 °C [77 °F] and 55 Gauss maximum over the full -40 °C to
   125 °C [-40 °F to 257 °F] temperature range, allowing for the
   use of smaller, magnets or a wider air gap
• Internal pull-up Hall IC design: Simplifies installation and
   helps reduce component count and system cost
• Bipolar latching magnetics: Makes these products wellsuited for accurate speed sensing and RPM (revolutions per
   minute) measurement
• Sub-miniature, SOT-23 surface mount package (SS360PT)
   supplied on tape and reel: Allows for compact design with
   automated component placement
• Small, leaded, flat TO-92-style package (SS460P): Allows for
   a compact PC board layout
• Wide operating voltage range of 3 Vdc to 24 Vdc: Allows for
   potential use in a wide range of applications
• Built-in reverse voltage capability: Enhances the protection
   of the sensor and the circuits
• Robust design: Allows operation up to 125 °C [257 °F]
• RoHS-compliant material meets directive 2002/95
