Methods and Apparatus for Sensor Having Fault Trip Level Setting

摘要

Methods and apparatus for a sensor having non-ratiometric fault trip level setting. In embodiments, a sensor has a sensing element with a fixed gain. A signal processing module receives the fault trip level setting and maintains the fault trip level setting constant during changes in the supply voltage.

1. A sensor, comprising:
a sensing element having a fixed gain; a voltage pin to receive a supply voltage; a fault trip level pin to receive a fault trip level setting; a signal processing module to receive the fault trip level setting and maintain the fault trip level setting constant during changes in the supply voltage; a fault output pin to transition to an active state based a signal from the sensing element and the fault trip level setting output from the signal processing module; and a sensor output pin to output data from the sensing element.
