Separated from the CAN Interface Operating Modes
• Low Speed 125 kBaud Fault Tolerant CAN Interface, Compatible
with 33388 Stand Alone Physical Interface
• V1 Regulator Monitoring and Reset Function
• Three External High Voltage Wake-Up Inputs, Associated with V3
VBAT Switch
• 100 mA Output Current Capability for V3 VBAT Switch Allowing Drive
of External Switches or Relays
• Low Stand-by and Sleep Current Consumption
• VBAT Monitoring and VBAT Failure Detection Capabilities
• 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
Cycle Wake
• INterface with the MCU through the SPI
• Pb-Free Packaging Designated by Suffix Codes VW and EG
