FS4503混合和动力汽车系统基础芯片(SBS)解决方案_技术

　　The NXP® FS4500 system basis chip （SBC） provides power to MCUs and opTImizes energy consumpTIon through a DC/DC pre-regulator and linear regulators and ultra-low-power saving modes.

　　The FS6500/FS4500 SMARTMOS devices are a mulTI-output， power supply，integrated circuit， including CAN Flexible Data （FD） and/or LIN transceivers， dedicated to the automoTIve market.

　　Multiple switching and linear voltage regulators， including low-power mode （32 μA） are available with various wake-up capabilities. An advanced power management scheme is implemented to maintain high efficiency over a wide range of input voltages （down to 2.7 V） and output current ranges （up to 2.2 A）。

　　The FS6500/FS4500 includes configurable fail-safe/fail silent safety behavior and features， with two fail-safe outputs， becoming a full part of a safety oriented system partitioning， to reach a high integrity safety level （up to ASIL D）。

　　The built-in CAN FD interface fulfills the ISO 11898-2 and -5 standards. The LIN interface fulfills LIN protocol specifications 2.0， 2.1， 2.2， and SAEJ2602-2.
