DESCRIPTION
The CH603/CH604/CH605 family is high performance ratiometric linear hall effect sensor, produced
with Bipolar technology; it is high performance small versatile linear Hall-effect devices which are
operated by the magnetic field from a permanent magnet or an electromagnet. The ratiometric output
voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. The
CH603/CH604/CH605 family has a quiescent output voltage that is 50% of the supply voltage.
The integrated circuitry provides increased temperature stability and sensitivity. The
CH603/CH604/CH605 provide high accuracy and temperature compensation. The linear hall sensors
have an operating temperature range from -40 to +150
℃
, appropriate for home appliances, industrial and
automotive environments. They respond to either South or North pole.

5. Function Description
The CH603/CH604/CH605 family MRL (Miniature Ratiometric Linear) sensors are small,versatile
linear Hall effect devices which are operated by the magnetic field from a permanent magnet or an
electromagnet. The ratiometric output voltage is set by the supply voltage and varies in proportion to
the strength of the magnetic field.
The integrated circuitry provides increased temperature stability, sensitivity and temperature
compensation. These linear position sensors have an operating temperature range of -40
o
C to
+150°C, appropriate for industrial and automotive environments. They respond to either positive or
negative gauss, monitoring either or both magnetic poles.
The quad Hall sensing element minimizes the effects of mechanical or thermal stress on the
output. The product providing a robust design over a wide temperature range. Rail-to-rail operation
(over full voltage range) provides a more usable signal for higher accuracy.
The CH603/CH604/CH605 family has a typical sinking or sourcing output of 1.5 mA continuous,
uses 4 mA of supply current at 5.0 volts and 25
o
C, and provides predictable performance over the full
temperature range. The CH603/CH604/CH605 family Series sensors have wider null and sensitivity
tolerances.
