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.
FS4503主要特性:
? Battery voltage sensing and MUX output pin
? Highly flexible SMPS pre-regulator, allowing two topologies: non-inverting buck-boost and standard buck
? Family of devices to supply MCU core from 1.0 V to 5.0 V, with SMPS (0.8 A, 1.5 A or 2.2 A) or LDO (0.5 A)

? Linear voltage regulator dedicated to MCU A/D reference voltage or I/Os supply (VCCA),5.0 V or 3.3 V
? 3.3 V keep alive memory supply available in low-power mode
? Long duration timer, counting up to 6 months with 1.0 s resolution
? Multiple wake-up sources in low-power mode: CAN, LIN, IOs, LDT
? Five configurable I/Os
FS4503應用:
? Drive train electrification (BMS, hybrid EV and HEV, inverter, DCDC, alterno starter)
? Drive train - chassis and safety (active suspension, steering, safety domain gateway)
? Power train (EMS, TCU, gear box)
? ADAS (LDW, Radar, sensor fusion safety area)
