FS6500

FS6500, FS4500 Safety power system basis chip with CAN FD and LIN transceivers Rev. 7.0 — 11 November 2020 Product short data sheet 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(13) and -5(14) standards. The LIN interface fulfills LIN protocol specifications 2.0, 2.1(23), 2.2(24), and SAE J2602-2(25). High temperature capability up to TA = 125 °C and TJ = 150 °C, compliant with AECQ100 Grade 1 automotive qualification. 2 Features and benefits 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 dedic...
