MICRONAS INTERMETALL

2

Hall Effect Sensor IC

in CMOS technology

Features:

– operates from 4.3 to 24 V supply voltage with reverse

voltage protection

– operates with magnetic fields from DC to 20 kHz

– overvoltage and reverse-voltage protection

– on-chip temperature compensation circuitry mini-

mizes shifts in on and off points and hysteresis over

temperature and supply voltage

– the decrease of magnetic flux density caused by rising

temperature in the sensor system is compensated by

a built-in negative temperature coefficient of hystere-

sis

– ideal sensor for speed measurement, revolution

counting, positioning, and DC brushless motors

– short-circuit protection

Specifications

– switching type: bipolar

– output turns low with magnetic south pole on branded

side of package

– output can change, if magnetic pole is removed
