Scalable PMICs power processors and peripherals
Summary
Applications such as ADAS, infotainment, virtual reality, pedestrian and gesture recognition are driving demand for high performance SoCs. A PMIC-based solution optimises supply voltage for the SoC and customises handshake and interface architectures to shorten the development cycle. These decentralised power supplies enable driver MOS stages to support high output currents for the processor’s computational. To be able to cover vehicle safety requirements, critical components/ functions have to be duplicated and methods for possible failure detection have to be implemented. There is also two-stage thermal monitoring with self-protection shutdown, two redundant voltage references and self-monitored dual clocking, as well as analogue and digital BIST functions.
