概览
NCV7192 is a Signal Conditioning Interface with Analog or SENT output, capable of Automotive Safety Applications. The IC receives a differential signal from the external sensing element, conditions gain and offset with a configurable amplification stage, compensates for sensor nonlinearity and temperature dependency, and delivers the result as digital SENT or ratio-metric analog output signal.
A separate measurement channel linearizes and measures the resistance of an external NTC to capture a medium temperature and communicate it over the SENT interface. The integrated EEPROM is programmable over the output pin for storage of configuration settings and compensation coefficients, as well as free format customer payload data. The NCV7192 includes failure diagnostics and internal protections against shorts, overvoltage, and reverse voltage to support Safety Applications.
