CH605

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.
