Description
The HX6388 is a CMOS progr ammable rafio metric linear
Hall Effect sensor IC. The linear output voltage is
proporfional口the magnetic flux density. The rafio metic
output volage is proportional to the supply vltage. AI the
parameters of the HX6388 transfer characteristic are flly
programmable. The Va, the sensitity, the slope polanity,
the output damping levels, and the themal sensitvity drit
are all programmable in end-user applications. The part
offers open-circuit, as well as over-voltage and under-
voltage detection and indvidual programming of ifferent
sensors which are in parallel 如the same supply voltage.
The HX6388 is programmable by mdulating the supply
voltage. No additional programming pin is needed. The
easy programmability allows a 2-point calibration by
adjusfing the output voltage directly to the input signal. In
addifion, the temperature compensation of the Hall IC can
be ft to all common magnetic materials by programming
first and second arder temperature coficients of the Hall
sensor sensitivity. This enables operation over the full
temperature range with high accuracy.
The sensor is designed for hostile industrial and
automotive applications and operates with typically 5 V
supply voltage in the ambient temperature range from 40
up口150 C. The HX6388 is available in the very small
leaded package SIP3-SA
