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 A) 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). (13) (14) The built-in CAN FD interface fulfills the ISO 11898-2 and -5 standards. The LIN (23) (24) (25) interface fulfills LIN protocol specifications 2.0, 2.1 , 2.2 , and SAE J2602-2 . High temperature capability up to T = 125 C and T = 150 C, compliant with AEC- A J Q100 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 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 Analog/Digital (A/D) reference voltage or I/Os supply (V ), 5.0 V, or 3.3 V CCA 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, DC-DC, 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)NXP Semiconductors FS6500, FS4500 Safety power system basis chip with CAN FD and LIN transceivers 4 Simplified application diagrams V V +battery PRE CORE VDD (KL30) VSUP3 FB CORE VSENSE VAUX E VAUX B COMP CORE MCU VAUX V AUX FCRBM SELECT V PRE VCCA E VCCA B CAN-5V VCCA VCCA AD ref.
