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).

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
   (VCCA tracker or independent), 5.0 V or 3.3 V
• Linear voltage regulator dedicated to MCU A/D reference voltage or I/Os
   supply (VCCA), 5.0 V or 3.3 V
