ZSSC3170
Automotive Sensor Signal Conditioner with LIN and PWM Interface
Brief Description
The ZSSC3170 is a CMOS integrated circuit for
highly accurate amplification and sensor specific
correction of bridge sensor signals. Featuring a
maximum analog gain of 420, as well as extended
offset compensation capabilities, the ZSSC3170 is
adjustable to nearly all resistive bridge sensor types.
Digital compensation of offset, sensitivity, tem-
perature drift, and nonlinearity is accomplished via a
16-bit RISC microcontroller. Conditioning coefficients
are stored in an EEPROM certified for automotive
applications.
Measured values are provided by one of the digital
LIN or PWM interfaces. Each interface can support
end-of-line calibration using the sensor output. Noise
sensitivity is greatly reduced because the calibration
equipment and the ZSSC3170 are mated digitally.
For quick and easy evaluation and support for
calibrating prototypes, ZMDI offers the ZSSC3170
SSC Evaluation Kit, which includes evaluation hard-
ware, SSOP20 samples, and software.
Features
Complies with LIN specifications 1.3 / 2.0 / 2.1
Configurable LIN publisher frame content
Data conversion rate of up to 430Hz fully utilizes
the maximum LIN channel capacity of 20kbit/s
PWM high-side and low-side switches, support
for LIN communication for end-of-line calibration
Digital compensation of offset, gain, temperature
effects up to 2nd order, and nonlinearity up to 3rd
order. Compensation of temperature sensor
offset, gain, and nonlinearity up to 2nd order.
