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.

用于汽車的傳感器信號調節芯片方案

瑞薩的傳感器信號調節器 (SSC) 解決方案具有極高的成本效益和靈活性。

視頻筆錄

我叫 Maria Agalidis,來自瑞薩電子。 今天我們來討論傳感器信號調節芯片方案。

車用傳感器的主要挑戰是捕獲模擬信號,并將其可靠地轉換為汽車微控制器的數字信息。

如今,我們的 SSC(傳感器信號調節芯片)能夠捕獲壓力和溫度,并將其轉換為汽車需要的精準信息。 盡管環境中存在各種挑戰比如 EMI、電壓降,噪聲等,我們的產品還是能夠準確轉換數據。

我們的演示是傳感器信號調節芯片在排氣系統等惡劣環境中運行的明顯示例。 在本演示中,我們可以看到兩個高溫探頭和兩個壓力傳感器,它們控制和監控排放微粒過濾器。 傳感器正在測量排放系統的效率,并且還會向控制單元發送各類診斷信息。 這個芯片為雙通道解決方案,能夠同時服務兩個檢測探頭。

因此該解決方案具有極高的成本效益和靈活性。 這就是為何一級制造商都在汽車的不同應用中使用這款 SSC(傳感器信號調節芯片)。
