Overview
The TLIN1028-Q1, specifically the TLIN10285DRBRQ1, is an automotive local interconnect network (LIN) transceiver developed by Texas Instruments. This component is designed to meet the stringent requirements of automotive applications, complying with the LIN 2.2A ISO/DIS 17987–4 standards and SAE J2602 recommended practice. It integrates a low dropout (LDO) voltage regulator, making it a versatile system basis chip (SBC) for various automotive systems.
The TLIN1028-Q1 reduces system complexity by providing a 3.3 V or 5 V rail with up to 70 mA (D package) or 125 mA (DRB and DDA packages) of current, suitable for powering microprocessors, sensors, and other devices. It features an optimized current-limited wave-shaping driver to minimize electromagnetic emissions (EME) and supports ultra-low current consumption in sleep mode, allowing wake-up via the LIN bus or the EN pin.
