ss360nt/ss360st/SS460S high sensitivity bipolar latching digital hall - effect sensor ics description the ss360nt/ss360st / SS460S high sensitivity bipolar latching digital h all - effect sensor ics are small, sensitive and versatile devices that are operated by the magnetic field from a permanent magnet or an electromagnet . they are designed to res pond to alternating north and south poles. the ss360nt is turned on by a north pole while the ss360st and SS460S are turned on by a south pole. the ss360nt/ss360st/SS460S offers reliable switching points with a high magnetic sensitivity of 30 g typ ical (5 5 g maximum). this sensor ic does not use chopper stabilization on the hall element , provid ing a clean output signal and a faster latch response time when compared to competitiv e high sensitivity hall - effect bipolar latching sensor ics which do use chopper stabilization. th ese products offer reverse polarity protection , deliver a st able output over a - 40 c to 150 c [ - 40 f to 302 f] temperature range, and can accept any dc supply voltage from 3 vdc to 24 vdc . for brushless dc motor manufacturers that need latching sensors with reliable, consistent performance for more efficient and smaller designs, honeywells new family of high sensitivity hall - effect bipolar latch ing sensor ics responds to low magnetic fields and offers consistent repeatability whil e delivering faster response times to a change in magnetic field for better motor efficiency . these hall - effect devices are available in two package styles : the ss360nt and ss360st in the m iniature sot - 23 surface mount package and the SS460S in the leaded , flat to - 92 - style package. the ss360nt and ss360st are available on tape and reel (3000 units per reel) . t he SS460S is available in a bulk package (1000 units per bag) . features and benefit s fastest response time in its class : provides more efficienc y in commutating a brushless dc motor no chopper stabilization: r esult s in a clean output signal high sensitivity: operate s from only 30 gauss typical, at 25c [77 f] and 55 gauss maximum over the full - 40 c to 150 c [ - 40 f to 302 f] temperature rang e, allowing for the use of smaller, magnets or a wider air gap bipolar latching magnetics: makes these products well - suited for accurate speed sensing and rpm (revolutions per minute) measurement sub - miniature, sot - 23 surface mount package (ss360nt/ss360st ) supplied on tape and reel: allows for compact design with automated component placement small, leaded, flat to - 92 - style package (SS460S): allows for a compact pc board layout wide operating voltage range of 3 vdc to 24 vdc : a llows for potential use in a wide range of applications built - in reverse voltage: enhances the protection of the sensor and the circuits durable design: allows operation up to 150 c [302 f] rohs - compliant material meet s directive 2002/95
