Renesas' best-in-class automotive sensor signal conditioning (SSC) ICs are optimized to withstand harsh automotive environments that require low supply current to reduce power consumption (critical for PHEV, BEV and FCEV vehicles), and provide excellent electromagnetic compatibility and ESD protection. In addition, these SSCs products offer digital compensation of inherent sensor offset, sensitivity, temperature drift, and nonlinearity covering a wide operational temperature range according to the AEC-Q100 standard (–40 °C to +150 °C).

In order to support ASIL requirements according to ISO 26262, multiple diagnostic and monitoring functions have been implemented on the SSCs to support OEMs and automotive sensor module suppliers. This ensures the SSCs support safety-critical sensor applications linked to transmission and braking, as well as other applications such as DPF, EGR and HVAC.

Renesas’ SSCs are compatible with multiple pressure sensor types, such as piezoresistive MEMS, ceramic and strain gauge for correct measurement of absolute, gauge/barometric and differential pressure. Renesas’ SSCs support high-temperature sensing using thermocouples.

These SSCs support various external temperature sensors, namely diode, RTD, TCR, and internal PTAT for correct temperature measurements. The output interfaces supported by SSCs include Analog, SENT, LIN, PWM, and I2C.

The end-of-line calibration of SSCs, supported via the output pin, uses one-wire interface (OWI) to reduce test time, ensuring calibration equipment communicates digitally. Digital calibration helps keep the customer’s overall assembly costs low, as trimming of sensing elements by external devices or lasers is not needed.  The new generation of SSCs enables customers to easily create a wide variety of sensor platforms by offering drop-in-compatibility and identical Pin & Pad layout when using the ZSSC41xx family.

The SSC evaluation kits are designed to provide an overview of the functions and configuration options for Renesas’ SSC IC family. These kits provide support for new and experienced users in the evaluation and design of their sensor modules.

用于汽车的传感器信号调节芯片方案

瑞萨的传感器信号调节器 (SSC) 解决方案具有极高的成本效益和灵活性。

视频笔录

我叫 Maria Agalidis,来自瑞萨电子。 今天我们来讨论传感器信号调节芯片方案。

车用传感器的主要挑战是捕获模拟信号,并将其可靠地转换为汽车微控制器的数字信息。

如今,我们的 SSC(传感器信号调节芯片)能够捕获压力和温度,并将其转换为汽车需要的精准信息。 尽管环境中存在各种挑战比如 EMI、电压降,噪声等,我们的产品还是能够准确转换数据。

我们的演示是传感器信号调节芯片在排气系统等恶劣环境中运行的明显示例。 在本演示中,我们可以看到两个高温探头和两个压力传感器,它们控制和监控排放微粒过滤器。 传感器正在测量排放系统的效率,并且还会向控制单元发送各类诊断信息。 这个芯片为双通道解决方案,能够同时服务两个检测探头。

因此该解决方案具有极高的成本效益和灵活性。 这就是为何一级制造商都在汽车的不同应用中使用这款 SSC(传感器信号调节芯片)。
