Short-Form Datasheet ZSSC4132 (Renesas)

Short-Form Datasheet ZSSC4132 Automotive Resistive Sensor Signal Conditioner with LIN Interface
Description Features
The ZSSC4132 is member of the Renesas’s family Differential bridge sensor input and on-chip or of CMOS integrated circuits for highly accurate external temperature sensors, selectable for amplification and sensor-specific correction of conditioning of sensor input signal and/or differential bridge sensor signals. Featuring a temperature output maximum analog pre-amplification in the range of Digital compensation of offset, gain, and higher 150 to 200, the ZSSC4132 is adjustable to nearly all order nonlinearity as well as temperature resistive bridges as well as voltage-source sensor coefficients of measured bridge sensor input types. signal Operating temperature range -40°C to 150°C Digital compensation of offset, sensitivity, temperature drift, and nonlinearity is accomplished Accuracy ±0.5% FS at -40°C to 150°C by a 16-bit RISC microcontroller. Calibration NVM memory for configuration and calibration coefficients and configuration data are stored in the data, and for configurable measurement and ZSSC4132 non-volatile memory (NVM), which is conditioning functionality reliable in automotive applications. LIN interface based on LIN Specification Package Measured values are provided via a LIN interface 2.2A according to the LIN Specification Package 2.2A. Supports output of one or more sensor signals The LIN interface enables transmission of sensor and product identification via a single LIN data as well as transmission of supplementary data. interface connection End-of-line calibration is also supported through this Configurable for nearly all resistive bridge output pin based on the LIN protocol. The sensors ZSSC4132 and the calibration equipment One-pass end-of-line calibration algorithm communicate digitally, so the noise sensitivity is minimizes production costs greatly reduced. Digital calibration helps keep No external trimming or components required assembly costs low as no trimming by external devices or lasers is needed. Supply voltage: 7V to 18V The ZSSC4132 is optimized for automotive Protection up to ± 40V (with external diode at VBAT) environments by overvoltage and reverse-polarity protection circuitry, excellent electromagnetic Input span: 1 to 900 mV/V compatibility, and multiple diagnostic features. Effective ADC resolution: 12 to 14 bit
Typical Applications
