35FS4500 - Grade 0 safety power system

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.

Key Features

  • with two failsafe 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 TA = 150 °C and TJ = 175 °C, compliant with AEC-Q100 Grade 0 automotive qualification. 2 Features.
  • Battery voltage sensing and MUX output pin.
  • Highly flexible SMPS pre-regulator, allowing two topologies: non-inverting buck-boost.

35FS4500-35FS6500-ASILD Grade 0 safety power system basis chip with CAN flexible data transceiver Rev. 4 — 5 August 2024 Product data sheet 1 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).
