Infineon SMD Hall Effect Sensor Switch

The Infineon high sensitivity automotive hall switch with direction detection is an integrated circuit dual Hall-effect sensor designed specifically for highly accurate applications which use a rotating pole wheel. Precise magnetic switching points and high temperature stability are achieved by active compensation circuits and chopper techniques on chip. The sensor provides a speed output at Q2 with the status corresponding to the magnetic field value. For positive magnetic fields exceeding the threshold BOP the output is low, whereas for negative magnetic fields lower than BRP the output switches to high. The output Q1 can be either high or low depending on the direction of rotation of the pole wheel. This direction information is calculated internally.

High sensitivity and high stability of the magnetic switching points
High resistance to mechanical stress by Active Error Compensation
Reverse battery protection
Superior temperature stability
Peak temperatures up to 195°C
