1. General description

The TJA1041 provides an advanced interface between the protocol controller and the

physical bus in a Controller Area Network (CAN) node. The TJA1041 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 TJA1041 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:

• 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

• Several protection and diagnosis functions including short circuits of the bus lines and

ﬁrst battery connection

• Automatic adaptation of the I/O-levels, in line with the supply voltage of the controller

2. Features

TJA1041 NXP Semiconductors High speed CAN transceiver 7. Functional description The primary function of a CAN transceiver is to provide the CAN physical layer as described in the ISO 11898 standard. In the TJA1041 this primary function is complemented with a number of operating modes, fail-safe features and diagnosis features, which offer enhanced system reliability and advanced power management functionality. 7.1 Operating modes The TJA1041 can be operated in five modes, each with specific features.

TJA1041 NXP Semiconductors High speed CAN transceiver 7.1.3 Standby mode The Standby mode is the first-level power saving mode of the transceiver, offering reduced current consumption. In Standby mode the transceiver is not able to transmit or receive data and the low-power receiver is activated to monitor bus activity. The bus pins are biased at ground level (via Ri(cm)). Pin INH is still active, so voltage regulators controlled by this pin INH will be active too.

TJA1041 NXP Semiconductors High speed CAN transceiver cleared. The wake-up flag is immediately available on pins ERR and RXD (provided that VI/O and VCC are present). The flag is cleared at power-on, or when the UVNOM flag is set or the transceiver enters normal mode. 7.2.5 Wake-up source flag Wake-up source recognition is provided via the wake-up source flag, which is set when the wake-up flag is set by a local wake-up request via pin WAKE.

TJA1041 NXP Semiconductors High speed CAN transceiver 7.3.3 TXD-to-RXD short-circuit detection A short-circuit between pins RXD and TXD would keep the bus in a permanent dominant state once the bus is driven dominant, because the low-side driver of RXD is typically stronger than the high-side driver of the controller connected to TXD. The TXD-to-RXD short-circuit detection prevents such a network lock-up by disabling the transmitter.

To ensure EMI performance in applications not using local wake-up it is recommended to connect pin WAKE to pin VBAT or to pin GND. 8. Limiting values Table 6.
