STMicroelectronics' L99PM62XP is an advanced power management chip for car body applications that optimizes overall system cost. The device addresses the challenge carmakers face in reducing the stand-by current consumption (quiescent current) at a time when the number of power-consuming products in the car is continuously increasing. It also provides comprehensive fail-safe functionality with reduced external components. The L99PM62XP provides a dedicated regulator with optimized dynamic behavior, enabling periodic system activation to monitor configurable wake-up sources, coupled with comprehensive diagnostic and system-status features. Addressing increasing system complexity, ST’s device integrates advanced fail-safe functionality to improve the sustainability and reliability of automotive electronic control units. The intrinsic fail-safe concept, including supervision of the microcontroller, supply voltages, and temperatures, prevents the system from locking up under all imaginable failure conditions.

Still riding on a separate hydroformed-steel ladder frame (itself redesigned and CAE-optimized for greater strength and lower mass), the new eight-passenger SUV sheds up to 300 lb (136 kg) compared with the incumbent model. The mass reduction enabled Ford engineers to move to a powertrain format using only the 3.5-L turbocharged V6 with auto stop-start and 10R80 10-speed automatic.
