NXP公司的FS4503具有CAN灵活数据收发器的Grade 1和Grade 0安全功率系统基础芯片(SBS),通过DC/DC预稳压和线性稳压器以及超低功耗节电模式来给MCU供电和优化能量损耗,最大输入电压36V,主要用在驱动列车电气化(BMS,混合EV和HEV,逆变器,DCDC),驱车列车底盘和安全(主动悬挂,转向装置,安全域网关),动力传动系(EMS,TCU,变速箱以及ADAS(LDW,雷达,传感器融合安全区)等.本文介绍了FS4503主要特性,框图和应用电路,以及评估板KITFS6522LAEEVM, KITFS6523CAEEVM和KITFS4503CAEEVM主要特性,框图,电路图,材料清单和PCB装配图.

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 part..
