BL Advanced Automotive Analog / System Basis Chip, 2x 5V/400mA LDOs, 4 wakeup, SOIC 32
Overview
The ® MC33904 is a device in the second generation family of system basis chips, combining several features and enhanced module designs.
* Works as an advanced power management unit for the MCU and additional integrated circuits such as sensors and CAN transceivers
* Built-in enhanced high-speed CAN interface ISO11898-2 and -5, with local and bus failure diagnostics, protection and fail-safe operation mode
* The SBC may include zero, one or two LIN 2.1 interfaces with LIN output pin switches and includes 2 or 3 wake-up input pins than can also be configured as output drivers for flexibility

## Features
* Voltage regulator for MCU, 5.0 V or 3.3 V, part number selectable, with possibilty of usage external PNP to extend current capability and share power dissipation
* Voltage, current and temperature protection
* Extremely low quiescent current in low power modes
* Fully-protected embedded 5.0 V regulator for the CAN driver
* Multiple under-voltage detections to address various MCU specifications and system operation modes i.e. cranking
* Auxiliary 5.0 V or 3.3 V SPI configurable regulator, for additional ICs, with over-current detection and under-voltage protection
* MUX output pin for device internal analog signal monitoring and power supply monitoring
* Advanced SPI, MCU, ECU power supply and critical pins diagnostics and monitoring.
* Multiple wake-up sources in low-power modes: CAN bus, I/O transition, automatic timer, SPI message and VDD over-current detection.
* ISO11898-5 high speed CAN interface compatibility for baud rates of 40 kb/s to 1.0 Mb/s
* This product is included in NXP®.s product longevity program, with assured supply for a minimum of 15 years after launch
