Features:
Description:
Each ratiometric linear Hall-effect sensor contains a monolithic integrated circuit on a single chip. This circuit
incorporates a quadratic Hall sensing element, which minimizes the effects of mechanical and thermal stress on
the Hall element and temperature compensating circuitry to compensate for the inherent Hall element sensitivity
change over temperature current.
These ratiometric linear Hall-effect sensors provide an output voltage that varies in proportion to the applied
magnetic field. The voltage output will increase in response to a south pole (positive) magnetic field applied
perpendicular to the package symbolization face, and will decrease in response to a north pole (negative)
magnetic field.
These 3150U ratiometric linear Hall-effect sensors can be used as a non-contact sensor for rotary and linear
position sensing and for current sensing.
Applications:
Ratiometric linear output capable of sinking and sourcing current
4.5 V to 6.0 V operation
Responds equally to positive and negative magnetic fields
Excellent temperature stability to operate in harsh environments
Robust package capable of withstanding harsh environments
Non-contact magnetic sensing
