Data Sheet: Advance Information

SBC Gen2 with CAN high speed and

LIN interface

33903/

33903/4/5

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

It combines several features and enhances present module designs. The device

works as an advanced power management unit for the MCU with additional

integrated circuits such as sensors and CAN transceivers. It has a built-in

enhanced high-speed CAN interface (ISO11898-2 and -5) with local and bus

failure diagnostics, protection, and fail-safe operation modes. The SBC may

include zero, one or two LIN 2.1 interfaces with LIN output pin switches. It

includes up to four wake-up input pins that can also be configured as output

drivers for flexibility. This device is powered by SMARTMOS technology.

SYSTEM BASIS CHIP

This device implements multiple Low-power (LP) modes, with very low-current

consumption. In addition, the device is part of a family concept where pin

compatibility adds versatility to module design.

32-PIN SOIC

The 33903/4/5 also implements an innovative and advanced fail-safe state

machine and concept solution.

Applications

• Aircraft and marine systems

• Automotive and robotic systems

• Farm equipment

Features

• 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

• Industrial actuator controls

• Extremely low quiescent current in LP modes

• Lamp and inductive load controls

• DC motor control applications requiring diagnostics

• Applications where high-side switch control is

required

• 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.

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

automatic timer, SPI message, and V_DDovercurrent 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
