STMicroelectronics has unveiled a new power management chip for car body applications. The device is said to address the carmakers' challenge to reduce stand-by current consumption (quiescent current) to preserve the energy stored in the car battery at a time when the number of power-consuming products in the car is continuously increasing.
ST's L99PM62XP power-management IC 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 integration of 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 is in production, with unit pricing of $2 for volumes in the range of 1,000 pieces
