描述 Description

The NXP? 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

特性 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
