BOOTS CORE SW CORE VPRE GATE LS BOOTS PRE SW PRE2 SW PRE1 VSUP2 VSUP1 NXP Semiconductors Document Number: MC34FS6407-08 Rev. 3.0, 7/2016 Advance Information Power system basis chip with high FS6407 speed can transceiver FS6408 The FS6407/FS6408 SMARTMOS devices area multi-output, power supply, integrated circuit, including HSCAN transceiver, dedicated to the industrial market. POWER SYSTEM BASIS CHIP 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 wide input voltages (down to 2.7 V) and wide output current ranges (up to 1.5 A). The FS6407/FS6408 include enhanced safety features, with multiple fail-safe outputs, becoming a full part of a safety oriented system partitioning, to reach a high integrity safety level. The built-in enhanced high-speed CAN interface fulfills the ISO11898-2 and -5 AE SUFFIX (PB-FREE) standards. 98ASA00173D Features 48-PIN LQFP-EP Highly flexible SMPS pre-regulator, allowing two topologies: non-inverting buck-boost and standard buck Applications Switching mode power supply (SMPS) dedicated to MCU core supply, from Automation (PLC, robotics) 1.2 V to 3.3 V delivering up to 1.5 A Building control (lift) Multiple wake-up sources in low-power mode: CAN and/or IOs Transportation (mobile machine, military) Six configurable I/Os Medical (Infusion pump, stairs) Linear voltage regulator dedicated to auxiliary functions, or to a sensor supply (V tracker or independent), 5.0 V or 3.3 V CCA Linear voltage regulator dedicated to MCU A/D reference voltage or I/Os supply (V ), 5.0 V or 3.3 V CCA Input VDD supply VCORE SNS MCU FB CORE VSUP3 COMP CORE VCCA E VSENSE VCCA B Vcca AD ref.
