Automotive Telematics Control Unit (TCU)

1. Overview

telematics-control-unit

A Telematics Control Unit (TCU) is an automotive ECU handling bidirectional communications between a vehicle and the outside world. A TCU enabling V2X (Vehicle-to-Everything) communications is essential in a connected car. TCU-equipped vehicles can provide functions such as emergency call (eCall), which is mandatory in Europe, OTA (Over the Air), which is used for maintenance and information updates, receiving traffic information and tracking stolen vehicles.
A TCU, the device enabling “Connected”, the “C” in the “CASE” acronym, requires stable communications.
ABLIC's lineup includes the industry's smallest connection diagnosis ICs for supplying power to GNSS antenna amplifiers, LDOs that supply clean power to communication chips, backup RTCs (real-time clocks) and the industry's lowest current consumption LDOs for powering backup RTCs. ABLIC provides a number of ICs suitable for a TCU.
