TJA1081BTS,118

Specialized Overview

The TJA1081BTS,118 is a FlexRay node transceiver compliant with the FlexRay electrical physical layer specification V3.0.1 and JASPAR requirements. It supports data transfer rates from 2.5 Mbit/s to 10 Mbit/s and operates within a VBAT range of 4.75 V to 60 V. The device features enhanced low-power modes optimized for ECUs permanently connected to the battery, including Sleep and Standby states. It provides differential transmit and receive capabilities with excellent EMC performance and ESD protection rated at ±6 kV per IEC61000-4-2. The component utilizes an SSOP-16 package (SOT338-1) and includes internal monitoring for voltage, temperature, and bus errors.

Specialized Feature Summary

• Compliant with FlexRay V3.0.1 and JASPAR 'Bus driver increased voltage amplitude transmitter' functional class
• Enhanced low-power management with local and remote wake-up support via dedicated data frames
• Integrated diagnosis including overtemperature detection, short-circuit detection, and supply monitoring
• Robust protection against ±6 kV ESD pulses and automotive transients according to ISO 7637 class C

Specialized Applications

• Time-triggered communication systems in automotive networks
• FlexRay network nodes requiring JASPAR-specific compliance
• ECUs permanently connected to battery supplies in 14 V, 24 V, or 48 V systems

Specialized Procurement Notes

Verify the specific ordering suffix to confirm the SSOP-16 package configuration. Confirm that the design accommodates the component's end-of-life status if long-term production continuity is required. Ensure compatibility with the host controller's VIO levels and validate that the system architecture supports the required FlexRay protocol specifications.

Specialized Selection Notes

Select this component when designing for FlexRay V3.0.1 compliance with JASPAR requirements. It is suitable for applications needing wide battery voltage operation up to 60 V. Consider its footprint compatibility with the TJA1081 and mode control similar to the TJA1080A. Verify that the host microcontroller can interface with the diagnostic pins ERRN and RXEN for proper state management.

Specialized Part Context

The TJA1081B is part of NXP's FlexRay transceiver family, designed as an advanced interface between the protocol controller and the physical bus. It is functionally and footprint compatible with the TJA1081 and supports mode control used in the TJA1080A. The device is specifically engineered to meet the stringent electromagnetic compatibility and power management demands of modern automotive Ethernet and FlexRay networks.

Specialized Replacement Considerations

The TJA1081G is the recommended replacement for new designs, as the TJA1081B does not have production continuity guaranteed by the NXP longevity program.
