ZSSC3154
Automotive Sensor Signal Conditioner with Dual Analog Output
Brief Description
The ZSSC3154 is an integrated circuit for highly
accurate amplification and sensor-specific correction
of a bridge sensor signal. Up to two temperature
sensors can also be read in parallel.
The circuitry provides different configurations of the
analog outputs to show two measurement results
simultaneously. This also allows generating a com-
plementary bridge sensor signal, which is often a
requirement in safety-relevant applications.
The ZSSC3154 can measure and process two exter-
nal temperature sensors to compensate the temper-
ature drift of the bridge sensor signal and to output a
separate temperature signal.
An integrated calibration microcontroller with an on-
chip EEPROM performs the digital compensation of
the sensor offset, the sensitivity, the temperature
drift, and the nonlinearity of a sensor signal.
The single-pass, digital end-of-line calibration com-
bined with the integrated broken-chip detection sup-
ports automatic and highly efficient mass production.
Features
Differential bridge sensor input
Half-bridge sensor or temperature sensor input
Digital compensation of offset, gain, nonlinearity,
and temperature dependency
Two analog outputs; behavior programmable by
EEPROM configuration
Sequential analog output mode provides two
measurement values at one output pin
On-chip diagnostic and safety features including
sensor connection diagnostic and broken-chip
detection
2 EEPROM words for arbitrary user data
Multiple configurable output options
Benefits
Bridge sensor signal validation for safety
applications via two antivalent analog outputs or
via half-bridge sensor measurement output
Simultaneous measurement of sensor signals,
including temperature signal for compensation
and for temperature output
Efficient use of non-calibrated elements for
bridge sensors and temperature sensors without
external trimming components
Single-pass end-of-line calibration algorithm
minimizes production costs
Excellent EMC/ESD robustness and AEC-Q100
