HAL115
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
