MCZ33903CP5EKR2

SBC Gen2 with CAN high speed and

LIN interface

The 33903/4/5 is the second generation family of the System Basis Chip (SBC).

It combines several features and enhances present module designs.

Features  MCZ33903CP5EKR2

• Voltage regulator for MCU, 5.0 or 3.3 V, part number selectable, with

possibility of usage external PNP to extend current capability and share power

dissipation

• Voltage, current, and temperature protection

• Extremely low quiescent current in LP modes

• Fully-protected embedded 5.0 V regulator for the CAN driver

• Multiple undervoltage detections to address various MCU specifications and

system operation modes (i.e. cranking)

• Auxiliary 5.0 or 3.3 V SPI configurable regulator, for additional ICs, with

overcurrent detection and undervoltage 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.  MCZ33903CP5EKR2

• Multiple wake-up sources in LP modes: CAN or LIN bus, I/O transition,

automatic timer, SPI message, and VDD overcurrent detection.

• ISO11898-5 high-speed CAN interface compatibility for baud rates of 40 kb/s

to 1.0 Mb/s

• Scalable product family of devices ranging from 0 to 2 LINs which are

compatible to J2602-2 and LIN 2.1

Applications  MCZ33903CP5EKR2

• Aircraft and marine systems

• Automotive and robotic systems

• Farm equipment

• Industrial actuator controls

• Lamp and inductive load controls

• DC motor control applications requiring diagnostics

• Applications where high-side switch control is required
