35FS4500, 35FS6500 Grade 0 safety power system basis chip with CAN flexible data transceiver Short data sheet: advance information Rev. 1.0 15 December 2017 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 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 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 = 150 C and T = 175 C, compliant with AEC- A J 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 and standard buck 36 V maximum input operating voltage Family of devices to supply MCU core from 1.0 V to 5.0 V, with SMPS (0.8 A or 1.5 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 A/D reference voltage or I/Os supply (V ), CCA 5.0 V or 3.3 V 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, IOs, LDT Five configurable I/Os 3 Applications T up to 150 C and T up to 175 C A J Drive train electrification (BMS, hybrid EV and HEV, inverter, DCDC, alterno starter) Drive train - chassis and safety (active suspension, steering, safety domain gateway) Power train (EMS, TCU, gear box)NXP Semiconductors 35FS4500, 35FS6500 Grade 0 safety power system basis chip with CAN flexible data transceiver 4 Simplified application diagram Figure 1.35FS6500C simplified application diagram - buck boost configuration - FS1B Figure 2.35FS4500C simplified application diagram - buck boost configuration - FS1B 35FS4500-35FS6500SDS All information provided in this document is subject to legal disclaimers.
