Specifications and information herein are subject to change without notice.

System Basis Chip with Low

Speed Fault Tolerant CAN

functions frequently used by automotive Engine Control Units (ECUs).

It incorporates a low speed fault tolerant CAN transceiver.

• Dual Low Drop Voltage Regulators, with Respectively 100 mA and

• 5.0 V Output Voltage for V1 Regulator

• Three Operational Modes (Normal, Stand-by, and Sleep Modes)

• Low Speed 125 kBaud Fault Tolerant CAN Interface, Compatible

• V1 Regulator Monitoring and Reset Function

• Three External High Voltage Wake-Up Inputs, Associated with V3

• 100 mA Output Current Capability for V3 V

• Low Stand-by and Sleep Current Consumption

• V

• DC Operating Voltage up to 27 V

• 40 V Maximum Transient Voltage

• Programmable Software Window Watchdog and Reset

• Wake-Up Capabilities (CAN Interface, Local Programmable

• INterface with the MCU through the SPI

• Pb-Free Packaging Designated by Suffix Codes VW and EG

The 33389 is a monolithic integrated circuit combining many
