ZSSC3015 RBicdLite-Auto™ Sensor Signal Conditioner with Diagnostics Brief Description Benefits The ZSSC3015 sensor signal conditioner IC is adjustable to nearly all piezo-resistive bridge sensors. Measured and corrected bridge values are provided at the Sig™ pin, which can be configured as an analog voltage output or as a one-wire serial digital output. No external trimming components required PC-controlled configuration and calibration via ZACwire™ one-wire interface – simple, low cost High accuracy (as high as ±0.1% FSO @ -25 to 85°C; ±0.25% FSO @ -50 to 150°C) Single-pass calibration – quick and precise The ZACwire™ digital one-wire interface (OWI) can be used for a simple PC-controlled calibration procedure to program a set of calibration coefficients into an on-chip EEPROM. The calibrated ZSSC3015 and a specific sensor are mated digitally: fast, precise, and without the cost overhead associated with trimming by external devices or laser. Integrated diagnostics functions make the ZSSC3015 particularly well suited for automotive applications. Features Digital compensation of sensor offset, sensitivity, temperature drift, and nonlinearity Programmable analog gain and digital gain; accommodates bridges with spans < 1mV/V and high offset Many diagnostic features on chip (e.g., EEPROM signature, bridge connection checks, bridge short detection, power loss detection) Independently programmable high and low clipping levels 24-bit customer ID field for module traceability Internal temperature compensation reference (no external components) Option for external temperature compensation with addition of single diode Output options: rail-to-rail ratiometric analog voltage (12-bit resolution), absolute analog voltage, ZACwire™ digital one-wire interface Fast power-up to data out response; output available 5ms after power-up Current consumption depends on programmed sample rate and mode: 1mA down to 300µA (typ.) Fast response time: 1.4ms typical High voltage protection: ≤ 30V with external JFET AEC-Q100 qualified Available Support Evaluation Kit available Mass Calibration System available Support for industrial mass calibration available Quick circuit customization possible for large production volumes Physical Characteristics Wide operation temperature: –50°C to +150°C Supply voltage 2.7 to 5.5V; with external JFET, 5.5 to 30V Small SOP8 package ZSSC3015 Application Circuit Vsupply +2.7 to +5.5 V VDD Sig™ OUT/OWI ZSSC3015 VBP Vgate VBN VSS 0.1 F Ground For more information, contact ZMDI via [email protected] © 2014 Zentrum Mikroelektronik Dresden AG — Rev. 1.12 —December 26, 2014.
