Overview

The TLIN14315RGYRQ1 is an automotive-grade LIN system basis chip (SBC) that integrates a LIN transceiver, a 5V LDO regulator providing up to 125mA, and a window watchdog supervisor. Designed for 12V automotive applications, it operates from a wide 5.5V to 28V supply range and includes a high-side switch with fault detection for controlling external loads like LEDs or sensors.

Why Choose This Part

This SBC reduces PCB footprint by combining power management, communication, and system monitoring into a single 20-VQFN package. It features ultra-low sleep current of 20uA and includes robust protection mechanisms such as 500mV receiver hysteresis, thermal shutdown, and TXD dominant time-out.

Applications

Automotive Body Control Modules
Ideal for door modules, seat controllers, and roof electronics requiring local power regulation and robust LIN communication.
Safety-Critical Electronic Control Units
Utilizes the integrated window watchdog and functional safety-capable features to monitor MCU health in ASIL-rated systems.
Automotive Lighting Systems
The integrated high-side switch and PWM channels allow for direct control of ambient lighting or indicator LEDs over the LIN bus.
