Safety Power System Basis Chip with CAN FD and LIN
Transceivers
Rev. 1.0 — 14 December 2017
Short data sheet: advance information
1 General description
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.
2 Features
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)
36 V maximum input operating voltage
Linear voltage regulator dedicated to auxiliary functions, or to sensor supply (VCCA
tracker or independent), 5.0 V or 3.3 V
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
3 Applications
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)
