Abstract

There are a wide range of core and emerging vision applications in the automotive industry. Core applications include front, rear, and surround-view cameras. Autonomous driving, mirror replacement, and driver monitoring cameras are some emerging applications as Advanced Driver Assistance Systems (ADAS) become more sophisticated. The automotive image sensor market has several key manufacturers with broad portfolios of sensors to address many of these applications. The portfolios range from low quality (1-2 megapixel image sensors) to high quality (8+ megapixel image sensors) resulting in different supply voltage, current, and power sequencing requirements.

The TPS650320-Q1 and TPS65033x-Q1 family of Power Management Integrated Circuits (PMICs) helps simplify the power design process for these cameras by optimizing solution size and enabling re-usability across many vision applications. The family of PMICs maintains strong performance against varying power requirements across existing and emerging camera applications. Each PMIC is also fully pin-compatible. Without the need for a power circuit redesign, a simple BOM change enables full power design scalability and re-usability from low-end non-functional safety cameras, to high-end functional safety cameras. This guide connects many common automotive image sensors to an appropriate PMIC part number. The part number is a Non-Volatile Memory (NVM) spin with default settings that support the sensor's power requirements.
