TJA1028T/5V0/20/1J

Drivers, Receivers, Transceivers Overview

The TJA1028T/5V0/20/1J is a LIN transceiver with an integrated voltage regulator, compliant with LIN 2.0/2.1/SAE J2602 and ISO 17987-4:2016 (12 V) standards. It features a 5.0 V regulator capable of delivering up to 70 mA. The device operates within a battery supply voltage range of 5.5 V to 28 V and supports a baud rate of 20 kBd. Operating temperatures span from -40 °C to +150 °C. Typical standby mode current is 45 μA, while sleep mode current is 12 μA. The component utilizes an SO8 package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated low-drop voltage regulator providing 5.0 V output with 70 mA capability
• Supports remote wake-up functionality via the LIN bus during Sleep and Standby modes
• Includes TXD dominant time-out function to prevent permanent bus blocking
• Robust ESD performance rated at ±8 kV according to IEC61000-4-2 for LIN and VBAT pins

Drivers, Receivers, Transceivers Applications

• Compact nodes in Local Interconnect Network (LIN) bus systems
• Powering Electronic Control Unit (ECU) microcontrollers and peripherals
• In-vehicle sub-networks requiring robust physical layer interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix /1J against official documentation to confirm any unique manufacturing or packaging specifications. Ensure compatibility with the required 5.0 V regulator variant and 20 kBd transmission speed. Confirm that the SO8 package aligns with the target PCB layout constraints and thermal requirements for the intended automotive application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this variant when a 5.0 V integrated regulator is required instead of the 3.3 V option. The 20 kBd baud rate designation indicates optimization for higher transmission speeds compared to the 10.4 kBd variants. Consider the SO8 package dimensions if board space allows, as the HVSON8 alternative offers a smaller footprint. Ensure the application benefits from the specific fail-safe features like loss-of-ground protection.

Drivers, Receivers, Transceivers Part Context

This component belongs to the TJA1028 series of LIN transceivers manufactured by NXP Semiconductors. The series includes variants with different regulator voltages (3.3 V and 5.0 V) and baud rates (10.4 kBd and 20 kBd). It is designed to facilitate compact node development in automotive LIN networks by combining transceiver and regulator functions on a single chip.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other TJA1028 variants such as TJA1028T/3V3/20 for 3.3 V regulator applications or TJA1028T/5V0/10 for 10.4 kBd operation. Cross-package replacements are available in HVSON8 format (e.g., TJA1028TK/5V0/20) for reduced board space requirements.
