Texas Instruments TLIN4029A-Q1 Automotive LIN Transceivers
Texas Instruments TLIN4029A-Q1 Automotive Local Interconnect Network (LIN) Transceivers with dominant state timeout and extended fault protection. These devices are physical layer transceivers with integrated wake-up and protection features. The TLIN4029A-Q1 transceivers are compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2 A, and ISO 17987–4 standards. These LIN transceivers are designed to support 12V LIN and 24V LIN applications with wide operating voltage and extended ±70V bus-fault protection. The TLIN4029A-Q1 also includes undervoltage detection, temperature shutdown protection, and loss-of-ground protection. These TLIN4029A-Q1 devices are AEC-Q100 qualified for automotive applications. The TLIN4029A-Q1 devices are ideal for body electronics and lighting, infotainment and cluster, hybrid electric vehicles and power train systems, and passive safety.
