TITLIN10283SDRQ1

Overview

The TLIN10283SDRQ1 is a Local Interconnect Network (LIN) physical layer transceiver with an integrated low-dropout (LDO) voltage regulator designed for automotive applications. It supports data rates up to 100Kbps and provides a regulated 3.3V or 5V output to power local microcontrollers, effectively reducing PCB complexity and component count. The device is AEC-Q100 qualified and includes extensive protection features such as 58V bus fault protection and thermal shutdown.

Why Choose This Part

This transceiver integrates a high-voltage LDO capable of delivering up to 70mA, allowing it to power an MCU directly from the automotive battery voltage. It features ultra-low power consumption in sleep mode (typically 17uA) and provides high electromagnetic compatibility (EMC) performance. The +/-58V DC fault protection on the LIN bus pin ensures survivability in harsh automotive electrical environments.

Applications

Getting Started

To evaluate this part, use the TLIN1028EVM evaluation module which provides easy access to the LIN bus, VSUP, and LDO output pins. When designing the PCB, place a decoupling capacitor close to the VSUP pin and ensure the EN pin is controlled by the MCU to manage power states. Refer to the TI LIN software library for driver implementation on standard microcontrollers.
