FS6500, FS4500

Safety Power System Basis Chip with CAN FD and LIN

Transceivers

Short data sheet: advance information

Rev. 1.0 — 14 December 2017

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 (V_CCA

tracker or independent), 5.0 V or 3.3 V

• Linear voltage regulator dedicated to MCU A/D reference voltage or I/Os supply (V_CCA),

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)
