Magnetic angle and rotation speed sensor with continuous and discontinuous modes of operation based on rotation speed of a target object |
摘要 |
A magnetic field sensor and a method used therein provide an output signal in angle units representative of an angle of rotation of a target of and also an output signal in speed units representative of a speed of rotation of the target object. A power control circuit can cycle a magnetic field sensor on and off in accordance with a sensed rotation speed of the object. |
