STMicroelectronics Unveils L99PM62XP Advanced Power-Management IC for Car Body Applications

The L99PM62XP Advanced Power-Management IC addresses the carmakers’ challenge to reduce 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 and optimized overall system cost. The L99PM62XP device 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. The new 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. The integration of cost-efficient peripheral functions, such as high-side and low-side gate drivers, operational amplifiers and auxiliary regulators, reduces the number of external components, optimizing overall system cost. The L99PM62XP offers compatibility with both LIN (Local Interconnect Network) and High-Speed CAN (Controller Area Network) automotive communication protocols for increased performance and versatility. The L99PM62XP advanced power management IC targets microcontroller-based automotive applications such as door modules, body control units and mechatronic subsystems…
