How to deliver current beyond 100 A to an ADAS processor

The electrification of vehicle systems is growing in advanced driver assistance systems (ADAS), which include vision analytics for autonomous driving, parking assistance and adaptive control functions. Smart connectivity, safety-critical software applications, and neural network processing all require enhanced computing power in real time. Meeting these advanced needs requires a multicore processor such as the TDA4VH-Q1, which can support electronic control units (ECUs) beyond 100 A. But the design challenges associated with high power include achieving efficiency for higher current rails, controlling thermal performance and load transients at full loads, and meeting functional safety requirements.
