TJA1028TK/5V0/20AZ

Drivers, Receivers, Transceivers Overview

The TJA1028TK/5V0/20AZ 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 operates within a battery supply voltage range of 5.5 V to 28 V and supports a transmission speed of 20 kBd. The device features a 5.0 V output regulator capable of delivering up to 70 mA. It is housed in an HVSON8 package (3 mm × 3 mm). Typical standby mode current is 45 μA, while typical sleep mode current is 12 μA. The operating temperature range extends from -40 °C to +150 °C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated low-drop voltage regulator providing 5.0 V at up to 70 mA
• Supports remote wake-up 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

Drivers, Receivers, Transceivers Applications

• Compact nodes in Local Interconnect Network (LIN) bus systems
• Powering Electronic Control Units (ECU) and microcontroller peripherals
• In-vehicle sub-networks requiring robust automotive interface solutions

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix AZ against the manufacturer's official documentation to confirm any unique packaging or environmental compliance specifications. Ensure compatibility with the required baud rate and regulator voltage for the target application design.

Drivers, Receivers, Transceivers Selection Notes

Select this variant when a 20 kBd transmission speed and a 5.0 V regulator output are required. The HVSON8 package is suitable for designs where board space is limited, offering over 70% reduction compared to SO8 packages. Confirm that the system requires the specific regulatory and EMC characteristics defined for the /20 series.

Drivers, Receivers, Transceivers Part Context

This component belongs to the NXP TJA1028 family of LIN transceivers. The family includes variants optimized for 10.4 kBd and 20 kBd speeds, as well as options for 3.3 V or 5.0 V regulators. The TK designation indicates the HVSON8 package type, distinguishing it from the standard SO8 plastic outline package found in other family members.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional substitutes within the same family include TJA1028T/5V0/20 (SO8 package) and TJA1028CTK (HVSON8 package, 5 V, 20 kBd). Verify package footprint compatibility when switching between SO8 and HVSON8 versions.
