产品特点 Features

Optimized for in-vehicle high speed communication

• Fully compatible with the ISO 11898 standard
• Communication speed up to 1 Mbit/s
• Very low ElectroMagnetic Emission (EME)
• Differential receiver with wide common-mode range, offering high ElectroMagnetic Immunity (EMI)
• Passive behavior when supply voltage is off
• Automatic I/O-level adaptation to the host controller supply voltage
• Recessive bus DC voltage stabilization for further improvement of EME behavior
• Listen-only mode for node diagnosis and failure containment
• Allows implementation of large networks (more than 110 nodes)

Low-power management

• Very low-current in Standby and Sleep mode, with local and remote wake-up
• Capability to power-down the entire node, still allowing local and remote wake-up
• Wake-up source recognition

Protection and diagnosis (detection and signalling)

• TXD dominant clamping handler with diagnosis
• RXD recessive clamping handler with diagnosis
• TXD-to-RXD short-circuit handler with diagnosis
• Overtemperature protection with diagnosis
• Undervoltage detection on pins VCC, VI/O and VBAT
• Automotive environment transient protected bus pins and pin VBAT
• Short-circuit proof bus pins and pin SPLIT (to battery and to ground)
• Bus line short-circuit diagnosis
• Bus dominant clamping diagnosis
• Cold start diagnosis (first battery connection)
