Renesas Electronics introduced the ZSSC4132 automotive single-package sensor signal conditioner (SSC) with an integrated certified LIN v2.2a interface. The device promises best-in-class performance, increased design flexibility, and cost efficiency in a compact form-factor for HVAC applications in plug-in hybrid electric vehicle (PHEV), Battery Electric Vehicle (BEV), and Fuel-cell Electric Vehicle (FCEV) climate-control systems. Configurable for nearly all resistive-bridge sensors, features include an integrated LIN PHY, a small package footprint, and AEC-Q100 Grade 0 qualifications. The SSC addresses small automotive sensor modules with limited space, tight budgets, and end-of-line (EOL) calibration requirements.
The ZSSC4132 offers a complete LIN-certified SSC solution that allows simple and cost-effective scaling for HVAC system development, serving mid-range up to high-end EVs and HEVs. The solution combines analog front-end (AFE) technology for enhanced sensor signal conditioning, as well as digital calibration to significantly reduce noise sensitivity for high accuracy in pressure and temperature readings. The SSC’s integration reduces overall bill of material (BOM) requirements by minimizing the need for external components. In addition, the ZSSC4132’s digital calibration feature allows customers to minimize calibration efforts, further reducing overall system costs.
Additional features include a differential bridge sensor input that enables accuracy at ±0.5% full scale output for temperatures ranging from -40°C to 150°C, 12- to 14-bit ADC resolution, and a remote node position detection feature at the LIN bus, allowing the SSC to assign a unique ID to the device. Overvoltage and reverse-polarity protection is standard. The ZSSC4132 is available now in a 4mm x 4mm, 24-lead QFN package with prices starting at $1.38 USD per unit in 10,000-unit quantities. An evaluation kit for the ZSSC4132 is also available now with prices starting at $185 USD.
