SS133 unipolar hall - effect digital switch 2 v2 . 0 0 may 1 , 20 12 general descri ption the SS133 is a uni polar hall - e ffect sensor ic fabricated from bipolar technology. the de v i c e i n teg r a t es a v o l ta g e r e g ul ato r , reverse battery protection diode, h a l l s en s or w i th d y na m i c o f f s et c an c e l l a t i o n s y s te m , temperature compensation circuitry, small signal amplifier, s c hm i tt t r i gger and a n open - collector o ut put to sink up to 50 ma. with sui table output pull up, they can be used with bipolar or cmos logic circuits. these hall - effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150 c ,and are mo re stable with both temperature and supply voltage changes. internal compensation characteristic makes the sensitivity increas e slightly with temperature increasing , so that this ic is particularly suitable to be used with the commonly low - cost magnets . if a magnetic flux density larger than threshold bop, output is turned on (low). when a magnetic flux density reversal falls below brp, output will be turned off (high). thanks to its wide operating voltage range , extended choice of temperature range and high reliability , it is quite suitable for use in automotive, industrial and consumer applications. glossary of terms millitesla (mt), gauss units of magnetic flux density: 1mt = 10 gauss rohs restriction of hazardous substances operating point ( b op ) magnetic flux density applied on the branded side of the package which turns the output driver on (v out = v dson ) release point (b rp ) magnetic flux density applied on the branded side of the package which turns the output driver off ( v out = high) free datasheet http://
