Renesas introduces Sensor Signal Conditioner for Electric & Hybrid Electric Vehicle HVAC Systems

RenesasRenesas Electronics Corporation has unveiled the ZSSC4132 – an automotive pressure sensor solution featuring an integrated certified LIN v2.2a interface.

The single-package sensor signal conditioner (SSC) provides best-in-class performance for HVAC applications used in plug-in hybrid electric vehicle (PHEV), Battery Electric Vehicle (BEV), and Fuel-cell Electric Vehicle (FCEV) climate control systems.

The product shall be configured for nearly all resistive bridge sensors. This flexibility combined with an integrated LIN PHY, small package footprint, and AEC-Q100 Grade 0 qualifications, makes the SSC ideally suited for small automotive sensor modules.

Christian Wolf, Vice President, Automotive Sensor Business Division, Renesas, said, “With the ZSSC4132, customers can access a complete SSC solution that is already LIN certified, allowing them to easily and cost effectively scale their HVAC system development for mid-range up to high-end EVs and HEVs.”


The SSC’s integration reduces overall bill of material (BOM) needs by minimizing the requirement for external components.

Apart from this, the ZSSC4132’s unique digital calibration feature which allows customers to minimize calibration efforts, further decreasing overall system costs.

Other features include LIN v2.2a certification with backwards compatibility to LIN v1.3, v2.0, and v2.1.

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.

Slave node position detection feature at the LIN bus, allowing the SSC to assign a unique ID to the device. Overvoltage and reverse-polarity protection circuitry.

The product is available now in a 4mm x 4mm, 24-lead QFN package with prices starting at $1.38 per unit in 10,000-unit quantities.

Renesas Electronics Corporation offers trusted embedded design innovation with complete semiconductor solutions. The electronic major’s solutions enable billions of connected, intelligent devices to enhance the way people work and live.
