Power System Basis Chip with High
Speed CAN Transceiver
FS6407
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
standards.
