Overview
The TJA1028T/5V0/20:11 is a LIN (Local Interconnect Network) transceiver manufactured by NXP USA Inc. This component is designed to meet the standards of LIN 2.0/2.1/SAE J2602 and ISO 17987-4:2016 (12 V), making it highly suitable for automotive electronics. It features an integrated low-drop voltage regulator that can deliver up to 70 mA and provides a regulated 5 V output. The transceiver supports a baud rate of 20 kBd and is available in both SO8 and HVSON8 packages, which are particularly useful for space-constrained applications due to their compact size.
