Magnetic Field Sensors and Related Techniques That Can Provide Self-Test Information |
摘要 |
Magnetic field sensor and related techniques can identify passing conditions, failing conditions, and marginal conditions of a sensed object. The magnetic field sensor and techniques can use one or more peak values of a proximity signal representative of proximity of the object, DC offset values of the proximity signal, or threshold values related to an amplitude of a signal representative of the proximity signal to identify the conditions. |
