35FS4500, 35FS6500
Rev. 1.0 — 15 December 2017
Grade 0 safety power system basis chip with CAN flexible
data transceiver
Short data sheet: advance information

General description
The 35FS4500/35FS6500 SMARTMOS devices are a multi-output, power supply,
integrated circuit, including CAN Flexible Data (FD) transceiver, dedicated to harsh
automotive and transportation markets requiring high reliability (Grade 0) and high
functional safety (fit for ASIL D) performance.
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 1.5 A).
The 35FS4500/35FS6500 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.
High temperature capability up to T
A
= 150 °C and T
J
= 175 °C, compliant with AEC-
Q100 Grade 0 automotive qualification.
