FS6500, FS4500: ASIL B Safety power system basis chip with CAN FD and LIN transceivers Rev. 3 14 April 2021 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 B). (12) (13) The built-in CAN FD interface fulfills the ISO 11898-2 and -5 standards. The LIN (22) (23) (24) 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: ASIL B Safety power system basis chip with CAN FD and LIN transceivers On board charger Motor control 4 Simplified application diagrams VPRE V +battery CORE VDD (KL30) VSUP3 FB CORE VSENSE VAUX E VAUX B COMP CORE MCU VAUX V AUX FCRBM SELECT VPRE VCCA E CAN-5V VCCA B V DEBUG VCCA CCA AD ref. voltage mode V CORE DEBUG VDDIO or V CCA ignition key IO 0 (KL15) MUX OUT ADC Input FS6500C IO 5/VKAM IO 4 Vstandby to switch MOSI CANH MISO CAN BUS SPI CANL SCLK NCS VPU-FS INTB NMI V DDIO RSTB Reset FS1B fail-safe delay TXD RXD CAN V DDIO IO 2 fail-safe FS0B drive IO 3 GNDA GND COM DGND aaa-037808 Figure 1.FS6500C simplified application diagram - buck boost configuration - FS1B FS6500-FS4500SDS-ASILB All information provided in this document is subject to legal disclaimers.
