Overview
The TJA1028T/5V0/20,11 is a LIN (Local Interconnect Network) transceiver manufactured by NXP USA Inc. This component integrates a LIN transceiver and a low-dropout voltage regulator into a single chip, making it highly versatile for automotive electronics. It is compliant with LIN 2.0/2.1/SAE J2602 and ISO 17987-4:2016 (12 V) standards. The device supports a baud rate of up to 20 kBd and provides a regulated 5 V output capable of delivering up to 70 mA. This product is particularly useful in applications where space is limited due to its compact packaging options, including SO8 and HVSON8 packages.
