TJA1041A
FEATURES
• Over-temperature protection with diagnosis
• Undervoltage detection on pins VCC, VI/O and VBAT
Optimized for in-vehicle high speed communication
• Automotive environment transient protected bus pins
and pin VBAT
• Fully compatible with the ISO 11898 standard
• Communication speed up to 1 Mbit/s
• Short-circuit proof bus pins and pin SPLIT (to battery
and to ground)
• Very low ElectroMagnetic Emission (EME)
• Differential receiver with wide common-mode range,
offering high ElectroMagnetic Immunity (EMI)
• Bus line short-circuit diagnosis
• Bus dominant clamping diagnosis
• Cold start diagnosis (first battery connection).
• Passive behaviour when supply voltage is off
• Automatic I/O-level adaptation to the host controller
supply voltage
GENERAL DESCRIPTION
• Recessive bus DC voltage stabilization for further
improvement of EME behaviour
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 EMC
performance, very low power consumption, and passive
behaviour when supply voltage is off. The advanced
features include:
• 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
• Low-power management, supporting local and remote
wake-up with wake-up source recognition and the
capability to control the power supply in the rest of the
node
local and remote wake-up
• Wake-up source recognition.
Protection and diagnosis (detection and signalling)
• Several protection and diagnosis functions including
short circuits of the bus lines and first battery connection
• TXD dominant clamping handler with diagnosis
• RXD recessive clamping handler with diagnosis
• TXD-to-RXD short-circuit handler with diagnosis
• Automatic adaptation of the I/O-levels, in line with the
supply voltage of the controller.
