0, 6/2019 Power system basis chip with high speed CAN and LIN transceivers 33907 33908 The 33907/33908 SMARTMOS devices area multi-output, power supply, integrated circuit, including HSCAN and/or LIN transceivers, dedicated to the automotive market.
Multiple switching and linear voltage regulators, including low-power mode (32 μA) 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 33907/33908 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 (up to ASIL D).
The built-in enhanced high-speed CAN interface fulfills the ISO11898-2 and -5 standards.
The LIN interface fulfills LIN protocol specifications 1.
