Power system basis chip with high
speed CAN and LIN transceivers
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 1.3, 2.0, 2.1, 2.2,
and SAEJ2602-2
Features
Battery voltage sensing & MUX output pin
Highly flexible SMPS pre-regulator, allowing two topologies: non-inverting
buck-boost and standard buck
Switching mode power supply (SMPS) dedicated to MCU core supply, from
1.2
V to 3.3 V delivering up to 1.5 A
Multiple wake-up sources in low-power mode: CAN, LIN, and/or IOs
Six configurable I/Os
Linear voltage regulator dedicated to auxiliary functions, or to a 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
