TJA1041A: High-speed CAN transceiver with standby and sleep mode

The TJA1041A provides an advanced interface between the protocol controller and the physical bus in a Controller Area Network (CAN) node. The TJA1041A is primarily intended for automotive high-speed CAN applications (up to 1 Mbit/s). The transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller. The TJA1041A is fully compatible to the ISO 11898 standard, and offers excellent ElectroMagnetic Compatibility (EMC) performance, very low power consumption, and passive behavior when supply voltage is off. The advanced features include:

sot108-1_3d

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)
